Mikael,
You might consider using a "solid state disk" or what is also called a
"flash disk" instead of a hard drive. Basically these are memory cards
that are non-volatile, so you can use them to hold your OS and boot off
of them like a hard drive and they retain stored information even after
reboots.
They typically have much less available space than a hard drive,
somewhere in the 2-100 MByte range, but this is usually enough for
specialized configurations like a FW or dedicated router, which is what
it sounds like your talking about.
This technology is what cisco routers and the cisco PIX use for example
to get around the moving parts issue.
You can take a look at <http://www.advantech.com> and see some examples
of these devices. I'm sure there are other companies that sell these
devices, that's just the web site I'm familiar with so don't take that
as an endorsement of their products.
If you used one of these devices for booting and holding your OS, you
could eliminate the moving parts issue your trying to avoid and a few MB
should be enough for specialized purposes. (trinux for example can run
off a floppy) The cards at this site support up to 144MB, which should
be more than enough for your purposes and is a much lower cost
alternative than purchasing a new router.

Anyone have a nice suggestion for some kind of device that'll do this:
At least one fastethernet-port, preferrably two.
encrypted tunnling
10-20 mbit throughput (or more) over the tunnel
OSPF speaker
no moving parts (harddrives etc)
flexible configuration when it comes to IP config/routing (multiple IP
adresses per interface (alias) for instance)
should handle it's tunnel being 1:1 statically address translated
somewhere along the way.
So far I have tried a linux machine running CIPE which pretty much does
this (I havent tried doing OSPF over the tunnel though) but it also
falls
into the "moving parts" category... I dont really like having a complete
OS like that on the device either.
I guess Cisco has something that'll do this but I suspect it'll be a bit
pricey. I really like the device to be in the price range of below
US$5000.
