From: "Vijay K. Gurbani" <[EMAIL PROTECTED]>

   We could nail a line in the sand and make this more concrete (i.e.,
   use between proxies only.)  Or we could take a middle road and allow
   implementors who have reflective connectivity between a UA and a
   (proxy) server use connect-reuse.  So far, the draft has been taking
   the middle road.

It's clear that connection-reuse can be done between a UA and a proxy
(or two UA's for that matter).  It doesn't solve the problem that
outbound solves, namely what if connections can only be opened in one
direction.  (connection-reuse implicitly assumes that whoever wants to
send a request first can open a connection.)  What we need to make
sure is that the two mechanisms don't interfere with each other.  This
probably isn't hard, no more than saying "if you're using outbound to
communicate with a SIP agent, don't use connection-use to talk to that
agent".
