Good idea. We're taking the opposite route, only allowing users to register on irc. We believe that on our network, given the option to register on the website would create a whole bunch of pointless never-used nicks that are just used by clueless web users who have no idea what theyre doing with irc ;-)
We're using our service to fetch certain information that is particular to the ircd and not services, e.g. output of /list, etc, so if there was a way to output this too -- i noticed chanserv only keeps a linked list of *registered* channels, which is the reverse of how our modified statserv works :)
Anyhow, have fun,
Brain :-)
