you could run it on an Urbane Tourist. It is a stock frame from the Urbane Cyclist, one of their urbanite line. It's made in the same factory as the Surly, though the frame while totally touring oriented is not the same as the LHT, it's more a classical touring frame, less MTB componentry.

I don't think any of the pictures show the horizontal axel plates, but that is what they are.
If you want 26" wheels, they have one like that also. The comuter format isn't all that encouraging but this is a touring bike. Of course there are lots of old MTB frames already available.

Urbane Cyclist sells nexus and Rohloff and know what it needs to mount it on a bike. Not a place to buy one cheap, but I think they were thinking of Rohloff when they designed this frame since it breaks with a lot of American touring bikes that have vertical plates.
