FWIW I’ve just successfully set up a dedicated IVC server based on CentOS Linux and WINE 1.7.x compiled from Source. Works great and doesn’t require a windows license.
Let me know if you need help or instructions and I’ll be happy to help.
I think it could be done with the native Linux TS server too but I have no idea where the IVC server gets its config from (like those default ports and virtual servers being created on startup).
Cheers, Uwe
