These seem to be nicely wrapped-up versions of the N2K to Ethernet bridge that has been talked about and that I've been writing myself for my own use.
At the moment the specifications on the protocol are still quite vague, and contain strange terminology (as Jeff Siegel pointed out on Panbo) where they talk about "HTTP Header" that looks like a reference to a NMEA 0183 style message (
