So Google Desktop is currently indexing my computer.  I'm at home now, but I'm hoping that when i get back to work it will be done and I can give it a try.  If it indexes our C++ and C# sources then it just might be the best thing ever.  Well, I lie.  It would be better it it worked a la iTunes or XCode which report results instantaneously while you're typing them.  But this is still a good start.
