synchronization

In a VOIP application, I have upto 3000 clients rsync audio files from there linux server in a daily, server is placed at a data center (10Mbps in/out bound), the server works as a VOIP sip server running FreeSWITCH (low ping latency should be ensured.)

Therefore I would like to have server side control of rsync which controls:

Limit total outbound bandwidth.
Limit total number of connections. (Reject clients while at max number of connection and let it retry after a specific time frame.)
OPTIONAL: list/kill individual connections.

Normally I would use ssh + rsync + pem_keys with some extra options, but above requirements are not feasible by simple command lines. Can anyone point me some direction. or show some scripts/tools? I would also probably integrate them and release on github. Thanks!
