Hi,
First of all let me introduce myself. My name is Willem van den Akker from The Netherlands. I am (almost) maintaining the Jabberd2 and Jabber-muc packages for Debian. After some mailings with Daniel I ended here. I am a Solution/Infrastructure Architect at a large ICT company.
I am a supporter of open source. I run a Jabber-server on a production server and have tested Jitsi with the Jabberd2 package. It is working well. Reason for using Jabberd2 instead of EJabberd is the installed size and language of Jabber. It is C and so a little footprint.
A big con for Jabber is the connectivity with Gtalk. Without a Google account one can talk to other Gtalk users. I am very disappointed that Google will stop the support for XMPP in Google Hangout.
I hope to exchange information on this list.
Greetings, Willem
