Don't some of the newer NAS devices include some media server capabilities? Maybe just an old or cheap router could could connect some NAS to the WDTV with no WIFI except for the occasional management chores from a PC that could just connect to that network when needed? (Target advertised a N150 router for $15 last week)
[Edit] Actually that was a dumb thing to say - no streaming capabilities should be needed for the WDTV to use a NAS...
