Well add another one to the list.
This doesn't look good. Just searched BPS.

Servers
Users are not permitted to establish servers on any BPS Networks connection without prior, written consent from BPS Networks. Types of servers specifically banned include, but are not limited to:
Sharing of files (ftp servers and peer-to-peer sharing software, such as Napster® or Gnutella® are examples)
Mail servers (SMTP or POP3/IMAP servers)
Web Servers
It looks as though you have to get special permission, otherwise they block p2p programs.
