Sort of.  Agent is currently hard-coded to use TCP4ClientEndpoint or 
SSL4ClientEndpoint; the factory that it uses to generate these endpoints is not 
publicly exposed.

However, Agent passes a reactor, so you can implement your own reactor 
(probably a wrapper) that implements connectTCP and connectSSL to resolve and 
connect IPv6 names, and that will work just fine, and you will be using only 
public APIs, so it's supported :).

Does that make sense?

At some point, Agent should be modified to use 
<http://twistedmatrix.com/trac/ticket/4859>, once that's done and committed to 
trunk.  I don't know if a ticket exists to do that yet.  If you have already 
checked and there isn't, please feel free to file one.
