If you could reduce the size and power requirements then it is much easier to build an armored enclosure. While searching for Cool Stuff for my Palm Pilot I ran across this site:
http://www.uclinux.org/simm/
.. it's a single-board PC running a Motorola Dragonball processor, 2M of Flash and 8M of RAM, Serial and Ethernet controllers, and 18-pins of general purpose IO, some of which can be used to drive an LCD display. All this is packaged on a little 30-pin SIMM module, and consumes 3.3 volts. The Dragonball CPU is what powers the Pilot.
It could run off rechargables, and have a really small power supply to connect to the grid (or even a small solar array would be more than enough to keep a set of rechargables topped off for a few days of cloudy operation).
Oh yeah, it runs Linux. Although it is very limited, at 8M RAM, it may be all you need. The only problem you need to solve is getting wireless to work with the board (maybe some of those unused I/O pins?).
Something that small could be totally encased in polycarbonate - that would eliminate any worry about condensation. Imagine the whole thing, solar panel on top, circuitry on the bottom, encased in a solid block of polycarbonate! Wonder what the MTBF of that puppy would be?
(guess the rechargables would have to be external, unless they come up with the NiEternity battery)..

288 megabits * 8 bits = 288 megabytes
x2 = 576
My guess for the wierd amounts is that they are building in parity.. 288 / 9 = 32
