The _simplest_ solution would be to mandate the use of a TCP-based TURN 
server to terminate the traffic, but basically all RTP stacks are 
designed with fixed-size buffers and other resource limits, and when 
these are exceeded they will simply discard data. So even this "simple" 
solution would require a vast engineering effort to produce "reliably" 
transmitted data in a format that almost no non-real-time software could 
consume (requiring all services to convert it into something else on 
their own).
