Yes, if you're scrounging old test equipment for $100 a copy.  If you have
chunks of gear that cost $10K each, then $100-200 for individual interfaces
might not be a bad thing, especially considering how much new GPIB cables
cost.  I'd much rather plug and unplug Cat5 network cables from a hub than
deal with a stack of 3 or 4 of those GPIB connectors.

Now that I think about it, if the LAN-GPIB adapter widgets did PoE, that
would  be even slicker.
