[Serusers] Asigning a Subscriber to a Specific rtpproxy

[Greger V. Teigre]

Hi Andres,
I've been playing with the same idea at one point.  I think I concluded that 
using mediaproxy, SRV and different domains for the user groups 
part1.domain.com, part2.domain.com etc would be the easiest. However, if you 
want to be able to descretely assign a user to a given proxy on some 
criteria, that wouldn't work.
    Hacking rtpproxy to be able to take a parameter to 
force_rtp_proxy("which_proxy"); would probably be quite simple. However, if 
you want the cvs head load balancing/failover, you also need the concept of 
a group. I've heard rumours that Maxim has stopped development on rtpproxy 
(certainly haven't seen him on the lists lately), so maybe rtpproxy needs a 
new maintainer ;-)
