Hi Jocko, hi fvdw,
just found the Zyxel 325v2 (1,6 GHz Processor/512 RAM) also powered by Marvell Kirkwood chipset.
As this NAS doesn't carry the stupid "firmware on the HDD" (I prefer "bring your own HDDs") it may be a resonable idea to invest some considerations in supporting this platform. This Zyxel case is btw a lot cheaper compared to Lacie (82 €) and it will enhance your user base most likely a lot.
What do you think ?
