Would it be the Sheevaplug
you are thinking of? There are a couple of others.
Rhakios, thank you so much. I couldn't remember any of them but yes, that was one of them. And I have a starting point for some searching now so thanks a lot!
I may get that one, but I'll continue to see if there's an even more convenient model. My fantasy is something that basically *is* a wall plug, with an ethernet connection and built in wifi. Fat chance eh?
