Hello,
First and foremost, thank you for building great software!!
Now for the question. I am currently running Vine Server 2.0 on OSX 10.4.8. I am able to connect to this computer from other macs across the net, however; when I try to connect from my Windows PC at work I am unable to connect. I get mostly timed out errors. I have tried the built in Remote Desktop software built into Windows, I have tried RealVNC viewer, TightVNC, and VNCviewer from the windows machine and none of them will connect? Any ideas? From the same problem PC I am able to remote out to other PCs over the net without problems, so it doesn’t appear to be any problem with that computer. And from the home Mac I am able to access it over the internet from other Macs so it appears the ports are opened properly? So at this point I am completely stumped. From what I read thru google, this forum, and all the other VNC software sites; it is supposed to be possible for Windows and OSX to VNC without problems. Any help would be GREATLY appreciated. As I am pulling my hair out at this stage. 
Here is the output from the server log:
