Rasputine was born to connect Moo/MUD/talkers to the XMPP network, but in fact its a generic Telnet-to-XMPP gateway. This opens up a lot of interesting use cases.
You could add a buddy for each router that you have. Or one for each perlbal/memcached admin interface.
The internals are still a bit messy but after a small cleanup, you could even have two users, with their own Jabber ID, sharing a telnet session to a router. A kind of Pair-Configuration session.
Just think of all the devices you have with a Telnet administration console: Rasputine should be able to handle it.
