Hi Björn,
Currently, Saros does not support any other network protocol and the architecture is not set up to accommodate this either as far as I know. (We have discussed adjusting the architecture to include an abstraction for the protocol as this is sensible anyways. This would allow us to also add other protocols. But it is still a long way off.)
Is the issue that the server has to be hosted company-internally? Because otherwise you could use our XMPP server '
saros-con.imp.fu-berlin.de' (or other any freely available Jabber server).
Best regards,
Tobias
