but i think that SIP also does use p2p connection from client to client,
at least if that is possible. one example of that not being possible is
when both clients are behind some kind of NAT (that is called "router"
most often), without support of upnp or similar.

skype will use some (non-NATed) users as servers to connect this two
clients together, without the need for some dedicated gateway servers
(that cost bandwith).

This would mean that we must only find some way to
connect two nat'ed users together ...
