In all of these situations, you'll probably want to
use a filesystem in RAM.  When I boot off the network
or from a flash disk, I load a compressed filesystem
into RAM and then use it from there.  Chances are you
will need to have a mountable filesystem on the flash
disk also, but it will be minimal and only contain
those things you need to boot and stuff you save 
locally between sessions.

You're right about spinning up the HDD on demand.  If
you have most everything that changes in RAM, you can
avoid the HDD spin until you really need it.  (I plan
to not have HDDs in my set-top boxes.)  I've tried
and tried to eliminate drive spinup on my laptops,
and it's a real pain.

With 1GB of RAM sometimes selling for ~$30 (Dell),
there is little need for an appliance like a DVB box
to run from an HDD.
