Low power weather station server Meteohub has been ported to SheevaPlug.
While Meteohub is available for NSLU2, ALIX-Boards, Fit-PC Slim, eboxes and VMware for a while, the SheevaPlug port is brand new and still a bit experimental. Processing power of SheevaPlug comes close to AMD Geode performance which is much better than what could be derived from good old NSLU2.
