Remote frontends should currently be working almost as well as local ones, 
with the exception of stuff like bookmarks, editing, channel icons, etc.

A frontend won't have to run on the same system as a backend.

Yup.  One backend server will be designated the master server, and all 
frontends will initially connect to that.  The master server should be the 
only one running mysql.

A backend must have a tuner card.

The master backend server will tell the frontend where to connect to for each 
file / live tv tuner.

Yup.  Just added a hostname field to the settings table earlier today.
