the "win32" folder is inside the knots_win.zip archive

and about the "best profile" for 3g Streaming:

This depends on 2 things: first: the available upload speed provided by your ISP and second is the available download speed of your Mobile Provider.

Test both (from the computer the knots server runs on go to speedtest.net and post the results, then do the same from the N900) and then we might be able to create a acceptable streaming profile for your needs.
