Why not create the servers necessary to do that; to allow off-line IRC, and deliver via push? There are folks already using a similar scheme - bouncers - to do that with existing IRC clients and servers, after all. Package that and sell it, and (if your end-user agreements are clear about the potential for dual-use of the servers) package and sell the feed, too. We considered running a service like this for Mobile Colloquy. We ultimately decided that it wasn't worth doing. Too many different IRC networks out there, too much potential for abuse. This page is slightly out of date, but explains our reasoning for not running a bouncer service on our own: http://colloquy.mobi/push.html http://colloquy.mobi/push.html Instead, we host a push server and let people use a bouncer that they host on their own for push. There's support for ZNC, Colloquy and irssi. Plus an SDK-type thing, so any other bouncer with a plugin system can, in theory, work.
