I tripped over http://www.replicanet.com/ while looking for photon docs and I was wondering if it would work with Unity as it has a dotNet option(I think). Has anyone tried to use it? I'd make my day to find out I could use it with Unity - mainly because its free .
I see a lot of C++ mentioned on the solution explanation page. if thats true that it relies on unmanaged code then you can only use it in standalone and only with unity pro Depending on what you want to achieve though it might be a good option, but the same counts for things like Lidgren, Sockets, Photon (which includes an expandable server backend) / Neutron or SFS Pro
