I tried the PC beta software from Nokia once, back when I had just gotten the N800. My understanding is that the beta programme is not available anymore, but the source for the PC program was there at the time and I remember downloading it. I never looked at it (as it was a Windows program and I don't use it much), but now I can't remember what it was called or where I stored it.. did anyone else look at the source? If so, did it give any clue as to what protocol is used? (for a potential re-implementation or Linux version)
