I've decided that I have dealt with lack of symlinks in WinXP long enough.
Apparently NTFS has the ability to make junctions, which is sort of close enough for my purposes. Problem is they didn't include the interface for setting it, so you either need to get their tools disc or download a program that does it.
NTFS Link is one of these programs. I'm wondering if it's good and safe. It does come from SourceForge, but I'm still skeptical as I've kept a relatively clean and fast running XP thus far and I don't want to change that.
I allocated a small C drive in XP because I hadn't planned to use it much (and I didn't for quite a while there) but I've been using it more and programs deciding their default directory and having user storage (e.g. My Documents, Appdata, etc) and downloads on the same space as the temp directory and the important system files is just total bullshit.
