As i understood, two p2p client users both behind firewalls can absolutely not download from eachother, right?

And as more people get broadband they also get stuck behind a ISP's firewalls with private ip's, that are out of the users control, (at least this is how things seem to be done in my country...) Now who are all those highbandwidth (5, 10 Mbits line) going to download from, modem and dsl users...

Eventually won't there be more firewalled users than unprotected will p2p work then??


No, i don't know anything about this subject, that's why i'm posting
