Technically that should be a mythmediaserver (i.e. it should run the 
mythmediaserver application and not mythbackend) since tunerless 
backends aren't supported.

Correct.

I do recommend using mythmediaserver, though.  It will be much lower 
resource than mythbackend would be and doesn't require your creating 
fake tuners (that will slow down scheduling and serve no useful purpose 
and require extra work and ...).
