I don't really think so... careers for ENTP's would best have a rapidly changing environment and constant stream of new challanges, without really any mundane, repetitive tasks in the mix.
While a professor at a university does provide very nice interaction with students, the ability to teach them how to do new stuffs, and so on... it's kinda... bleh. The rest of the job sucks; the research parts, the heavy detail laden work, the things like getting referances and going over people's papers to ensure that they really DID give 'real' referances, the dealing with the fact that the professor MUST teach certain things according to the government, even if it's total crap, and so on.
In short, it looks good on the surface until yeu actually get into the real stuff. If yeu just want to teach and lecture people all day about yeur ideas, traditional schooling is *NOT* the best option for an ENTP at all because it fails hardcore on so many levels.
The best careers for long term choices, would be ones which are in the IT field in one way or another usually, technology is rapidly growing, and changes constantly. There's always a new problem, a new program, something new to be applied, new to be learned, and rather than the whole "read through mountains of useless crap" kinda dealie, it's more often a topic of interest to the ENTP, meaning they'd generally enjoy the learning process most of the time.
Everything from network security, to digital art design, to robotics, these are great things as they require constantly shifting one's information to match the criteria at hand.
Personally I'm going into 3D digital art design with an emphasis on video games; as the average user's computer gains in processing capacity, especially on the graphics card side, the stuff that one can do goes up massively. There's everything from character animation, to character design, level design, pre-rendered graphics, to the neat part of trying to be sneaky in making things 'look' better than they really are, using tricks of the eye or processor to imply information which really isn't there. Take a look at WoW sometime; even if yeu hate the game, yeu have to admit, that they've managed to provide incredably pretty graphics despite that it can be run on a piece of crap for a computer... how? Because they use very low polygon count, use textures to fake details, that kinda thing, this sort of stuff is really rather interesting because of how much knowledge and puzzle solving it requires.
And better yet, my ending goal for my career, is to actually be on the lead design team for blizzard <3 So there'd be constant evaluation of game mechanics, code, graphics, balance issues, hardware compatibility, and so on. Trying to fit everything together in the end so that it makes sense would be tricky but so great too; for example, ENTP's will generally get bored easily on the whole 'details' part... so they LOVES the fun part of figuring out problems, or designing something new... once they have that down though, having to repeat the process ad nausia is just bleh.
So let's take the animation position; figuring out how to make something look better by lighting and texture effects is challanging, and innovative. Creating a unique level design based on both fun AND neat archetecture styles, especially if they're not found in history (skytown in metroid prime 3 is a great example of this), can be very great. Until... yeu get into the repetitive task of "design this entire level... by yeurself" then it's like oh joy this'll be... 'fun'.
Rather, the preferable spot would be the lead art designer then, able to sketch out a concept they have, or make one or two models to give an idea of whot they're looking for, then provide that to their team to do the little detail work of making the thousands of models actually required beyond that point. The idea of being able to encourage people with new ideas, go around helping them out where stuck, providing another point of view, but still getting last say on how it looks is nice. Problem is... paperwork, yay, but every job has it's downside or it wouldn't be work now would it?
The biggest thing to consider is whether it's worth the 'work' part and whether there's enough of the 'fun' part to go with it.
Being able to CREATE something is also pretty important, osmething that can be shown off or given to others, but maybe that's just me, not sure if it's a typical entp preferance for work.
