transfer server

[Ivan R. Judson]

Just so you all know what I've just done :-)

I'm planning on us having the transitional server on vv2.mcs.anl.gov, using
ports 9000 (Venues), 9002 (EventService), 9004 (TextService), and 9006
(DataService).

I've sent mail asking for these conduits to be put in place, anticipating
I'll get my stuff done tonight, checked in and Bob can resolve conflicts
before noon-ish tomorrow -- giving Ti enough time to release engineer this
weeks alpha.

One key thing that will make it easier for everyone in this release, we
should have the client profile default set to
https://vv2.mcs.anl.gov:9000/Venues/default (aka The Access Grid Lobby, on
the transitional server).
