You could read the archives from a week or 2 ago under the heading:
   Build your own "appliance"

I use these deices, but I unload them entirely into RAM.

I have seen devices (eary mikrotik routers?) with them as live (and ext3 
no less!) filesystems, but I would be very concerend about their lifespan.

One thing to note and this might well shaft you is that they use POI mode 
rather than DMA (or at least the ones I'm using do) so they will really 
crowbar the bus & cpu when doing transfers to/from them, however with only 
4-6 people and not doing much like writing voicemail, etc. you may not 
notice it.

If you're sticking a "normal" disctibution on it, I'd suggest dumping the 
DOM and getting a laptop type IDE/SATA drive and using that instead. It's 
not silent, but will be very quiet.
