Hooray. :) One thing that concerns me is that these won't be serialized
correctly. I -thought- you might be able to drop the resulting connector
into theApplication.tcpConnectors by hand, but at a closer look it doesn't
seem that would work. Does anyone have any ideas on this? Since
connectTCPService does depend on t.names, I agree with itamar that it isn't
appropriate for inclusion in t.internet, which rules out changing
Application to suit it specifically. Perhaps a general interface for
user-specified connector functions? Something like...
app.connectWith(connectTCPService, 'service', 'domain', ...)
so that the call info could be serialized and re-invoked on the next run.
