Hi Alessio, Since the number of ports available for users is between 1024 and 65535 from the start you get an upper bound of about 64000 p2p connections.
Furthermore, most cheap routers come with quite serious memory limitations and performance issues if the number of connections reaches a certain threshold. My noname router for example is in the hundreds (opening up a few (1-2) hundred connections pretty much freeze it up). Another issue that you need to consider is firewall filtering. Even if the hardware could teoretically cope with the load, in practice its never going to get it. Anyway I do believe that your question is a bit too general...

Thanks in advance for any comment or reference to some material. -- Alessio Pace. _______________________________________________ p2p-hackers mailing list p2p-hackers@lists.zooko.com http://lists.zooko.com/mailman/listinfo/p2p-hackers
