Of course, if I end up doing it I will finish it till it's done. Isn't
that one of GSoC's purposes, to stay involved even after the program
ends? But obviously I still need to accomplish things during the
program so that's why I'm still doing research on it, to see how much
time I might need to get at least something done. I'm OK with the
basic COM stuff. IUnknown doesn't scar  e me :) But for more advanced
stuff, I'm sure I'll need to ask around.

Thanks!
