I believe that's the case. I think it was covered in a different post...the old EQ1 teleporters would zip you to the Nexus (picture a bus transfer station) where you could take teleporters to other places.
If I recall, the ground-based porters operated every 15 or 30 minutes. So you would have to sit and wait for it to activate, be inside the arch, and away you go.
I'll bet the EQ2 version will have similiar ground-based porter arches, but be a bit faster, probably instantaneous.
