The basic problem is that the RealAudio protocol runs the data
through UDP ports. To be used inside a firewall either the
UDP ports must be generically allowed (thus opening the entire
internal network to UDP attacks) or a proxy must be written
to pass the traffic.
Since Progressive Networks is very concnerned about protecting
it's protocol it is unclear how much security they have implemented
to help alievate security concerns.
