About the network!

[LuisCarlos-Maia]

I understand that peer to peer is a direct connection between peers and that you need a server for that just to provide the id of the peers! but Geckos how does it work?
is the server like a peer host? where other peers connect?
what is the limit of ccu that the server can support?
peer to peer generally from what I've read supports 250 to 500 simultaneous connections
