No, yours wasn't a stupid question, and that was a sensible answer on my part, so I honestly can't see why you seem to take umbrage with it.

If you want to make one, go ahead, I'm not stopping you - but like I said, you will spend many times more on your little project than what I pointed out was a readilly available, good, feature rich and very cheap solution to a complex problem. Interfacing Ethernet across power lines is not someting for a novice, if you suddenly stop posting, then we'll know why.

Oh, and thanks for the info Melanie... You're welcome, next time I won't bother replying on this forum...
