That's probably reasonable. In north america at least, 5.1 setups are 
being pushed really hard for DVD-based home theatre, so a lot of people 
will have 5 speakers (usually three of them particularly crappy) and a 
subwoofer. But they're not especially well placed in the general case.

Let me know how it turns out. I was expecting you'd need 6 or 7 
ambisonic channels because of resolution 5.1 concentrates on the screen 
area.
