HOWTO: Transfer rate cap / bandwidth limitation [HELP]

Hello people,

I've started to develop a application in java to do audio and video streaming (javascript player posting request to http urls (apache) and struts namespaces to find resource files).
I'd like to be able to monitor each connection from a different user, as well as limit the bandwidth per user (both TRANSFER RATE as well as TOTAL BANDWIDTH ammount).

Any ideas on how to do this with tomcat?
I may start using tomcat and grow into jboss, dunno for sure if tomcat is fully configurable inside jboss.

Thanks,

Carlos.
