So with the impending release of 5.0 does anyone know if the (beta) IM service that is included will be externally accessible using Pidgin / Adium and what server they are basing it on, although it is nice having it built into the web client, it would be better for where I work if I can just open the relevant port on the server and have everyone connect to the server using an IM client.

(also means I can then easily get away with blocking all external IM servers)
