On issue, there is only 1 usb bus on the PI, and that also runs the
network, so the
usb tuners and the network feed to the NAS would be shared.    On high
bw things
I had difficulty getting it to work (usb cam saving images on network
with motion), but
after finding some usb driver parameters was able to get it to work.

Not sure about the issues on getting many tuners to run on backends, I
have been running
for quite a while 3-5 tuners on a single backend, 2 of the tuners are
PCI/PCI-e and 2 are
network attached HD Homeruns.     And that same backend also runs all
of the raid disk
that are being used, and mysqld, and that backend is not especially
powerful (dual
1.6ghz Atom) with 3.5gb of usable ram, and that reliably works and
records things, the
only issues I have ran into are around the underlying sata controller
cards...basic learning
is if you can use the ones build into the motherboard...they are more
reliable and almost
always faster and better tested (esp since they MB ones build in were
either made by Intel
or AMD).    The baseline Atom board with a good power supply runs
about 30-40W at idle,
the biggest power consumption plan is to boot the box of SSD and put
mysqld and similar
on the SSD and then put the rest of the storage on spinning disks that
should be spun
down when not needed.
