so in worst case you need 2 pipes meaning 4 fds

You just validated my point. A single bridge connecting two sockets
requires two pipes, one for each direction between the sockets. This
turns the '2 fds required' for a bridge into _6_ fds.

You're right but only in the case that when you have separtae briding
threads for each direction.<br>
I was thinkin about situation when there is ONE briging theard for two
directions. The you can you the same pipe<br>
for both direction.<br>
BTW thinking abouti it some more we could have ONE therad executing
MULTIPLE bridges....<br>
In this case you cane use the same pipes for ALL bridges. This could be
really BIG optimization.<br>

Sure, but it is no different frm are tech_specific bridges... in
order to use tech-specific bridging the stream format must be identical<br>
