Australian dollars mate, an Ion solution is $360 + RAM (say $40 for 2GB in
my currency) + HDD (say $50 for either the smallest hard drive I can find or
a USB/CompactFlash solution. I'm booting my laptop from USB at the moment to
test the theory, works pretty nicely, actually. It's great to be able to put
GRUB on the USB key, so it boots Mythbuntu if the key is in, and Windows
otherwise.).

So yeah, say $450 over here. Otherwise, yes, that's exactly what I plan to
build for the other frontend, VDPAU is working a treat on the current
machine.

I don't know about that but you would have to be doing several HD

Guess I should try it and see! Not much content is broadcast in true HD
here, most of our HD channels are just poorly upscaled versions of the
respective SD channels 90% of the time, but I still want the solution to be
futureproof. The NAS is gigabit. I can't remember if the switch is, I have
one that is and two that aren't.

I would be interested in the details of this also. My understanding is

Yeah. It'd be nice if the constants it uses in determining that could be
exposed to the user as a setting which allows you to weight storage
manually, allowing you to force the system to use the NAS equally, or even
preferentially, if the user preferred. But I don't think anything like that
is planned.
