Hi all.
	I've a question regarding the concept of Translator refered in the RFC 1889.
	What I've understand from this is that it was made to allow RTP / RTCP data to cross firewall. But does it solve the problem of dynamic port negociation that are present when you decide to do some streaming ? The exemple give in the RFC just concerne multicast.

	Is there someone to give me hint or clear examples about Translators ?
	When and where are they used ?
	What concrete implementation exist ? any product name ?

Really thanks.
