You still need a VPS or server of some kind, but if the "screen with irssi/weechat" concept sounds too much like 80s UNIX, there is quassel[1].
It's like a relay/proxy/bouncer but actually uses its own protocol between the GUI and core, so you get infinite backscroll, proper sync when running multiple GUI instances at the same time etc. Oh and there is a decent Android client called quasseldroid.
