There's nothing fundamentally stopping you from using an Ion system as a
combined frontend/backend. Recording an MPEG2 stream straight to disk
doesn't take much CPU. Neither does playback using VDPAU. Program listing
processing (mythfilldatabase) and commercial detection are reasonably
intensive, but with Myth's default settings, jobs should just take longer
rather than bringing the system to a halt.

Others who are actually using Ion systems as FE/BE systems can probably be
more specific, but it seems to me that the dual core Ion systems should make
an adequate backend for a single tuner system.
