[NateCCIE]

But you could point the expressway c to a special dns server for just it that has the srv record. ;)

Idea would be if I signed into jabber as ealeatherman at jabber.wvu.edu it would force it over to expressway. Running into lots of challenges here and starting to wonder if this is even possible.
