My thought on this is that Reactor and Application should both have
"listenString" and "connectString" methods which take a host/port/transport in
some sort of string syntax which we can specify on command lines.  So you could
say... connectString("tcp:8080:localhost") or listenString("ssl:8080").  I
haven't fully thought it out and I didn't want to try to rush it in before 1.0
and then change it around lots later, but I think this approach in general is a
necessary one (otherwise we'll end up implementing this mktap functionality you
describe everywhere that you want to open a socket).
