No registry

[Brainz]

due to computer problems, I've been unable to use my own computer. However, as I'm at uni, theres computers available 24/7. I've found solutions to most communication networks (trillian), but because I've not got the correct priveledges, I've not been able to install anything that adds to the system registry.
I know its a vital component of windows systems, but would it be possible to write a version that does not require read/write access to the registry at all?

That's a very good question... since the TS2 client comes with a set of codecs it is probably inavoidable, after all you need a way to tell Windows about the new codecs and where to find them I think.
