Every network I have connected to has allowed BNCs, either from my own use of one, or the fact I've seen other people on the network using them. Certainly, as far as I know, the top 4/5 networks allow connections from BNC.
You may run in to trouble if several people are using the same vhost. Even though IRCops can invariably see the REAL IP/hostname of the user, so can tell if it's really clones or not, people using the same vhost may *still* be banned.
You shouldn't run in to too many issues though!
You are of course welcome for all help given
Regards,
