Yes you can write to flash. Compact flash actually has an IDE
controller built in, so you can treat it just like a hard disk.
However there are (albeit high) limits on the number of times
you can actually write to a particular address so the software
has to take account of this (for e.g. putting swap on flash
will probably break it very quickly).

To blatantly plug our box, we have a 1U integrated appliance
which has NO MOVING PARTS. I.E. no fans, harddisk, ...
The interesting bit is it uses LVS, which of course any of
our modifications are GPL'd (some of which we've pushed back
to this list last week). Our box integrates stateful firewalling
+ LVS + VPN which is hard, trust me. And it's presented to the
user in a simple web interface.
