[cisco-voip] IM&P - Jabber for Everyone, MRA and private/public IP addressing

[Lelio Fulgenzi]

Just curious what people's thoughts are about Jabber for Everyone, MRA (via expressway) and private/public IP addressing of the presence servers. I've tried to find some documents that explain things, even in summary format, but with no luck. 

My (random) concerns: 





- does expressway support third party xmpp clients? 

- does expressway support jabber for everyone? (IM&P only) 

- does expressway scale to the possibly 25,000 IM users I might have? 

- expressway does not support all the on premise features, like file transfer 

- do i use private or public IP addresses? 
- no real details on how to deploy presence server on public IP but still use expressway for UC 


Any ideas or pointers would help... Thanks! 

Lelio
