the answer is yes.
Put in the IP address in the client version. You host or have a host for the server version. Nothing stops this version from anyone writing a server using C2 code. Once you achieve P2P, you can just set up one pear as a server.
The requirement for coding a server in another language has been the only hurdle for C2 online service. It could be done by anyone to do online. It's just that most C2 devs would rather use C2 to write a server. so we are a go now.
I'm looking forward to brain explosions people are going to have when it's releasef and find the complexity of network games :D
