I'm looking for a device with the following properties:

  - absolutely silent
  - as small as possible
  - two 10baseT (optional 100baseT) connectors
  - one PCMCIA (or cardbus) slot (needs to take a wavelan card)
  - some small amount of persistent storage (8 or 16 MB will do)
  - runs NetBSD

Since Sharks are not buyable any more and miss the second ethernet connector,
the best I could come up with is an old 486 machine, disk ripped out, booting
from floppy, mounting root on CD, maybe with special power supply (to make it
silent enough), two ethernet cards and two ISA<->PCMCIA adaptors one for the
wavelan card, the other for some flash/solid state disk. (I have most of this
lying around, so this would be a quite cheap solution, but probably not
silent enough - and it's big)

This box needs to be placed in my living room (don't ask), connect to a DSL 
modem with one of the ethernet cards and be a router, NAT, ipf box; maybe
running dhcpd for the internal ethernet and additionally some small, custom
daemons. If it can take an ISDN card it will become an answering machine too.

Ideal think would be something like an Apple AirStation with second ethernet
and running NetBSD ;-)


Any hints?
