Success would depend on getting vendor software to recognize the data in IP form, that means writing or supplying drivers - unless you are talking about writing charting software too in which case this conversation will become much more interesting to me.
Most available chart/ECS packages support NMEA over TCP or UDP (or both) (well, at least all those that I had a chance to explore, MacENC, Coastal Explorer, Fugawi, Maxsea, and many others).
For the rest (if they exist), it is trivial to provide serial to TCP gateway, so if there was an interest per se, we'd certainly come up with a complete solution if the software side would be best served in this manner.
That said, it will also talk to our own ECS software, but this is beside the point (and for practical purposes we can assume it does not - I don't expect current users to drop their favorite ECS system).
That said, I'd say that extrapolating from Sailnet total user population, any less than, say, 20-30 answers of "yeh, this sounds like a nice device to get" would probably indicate the market is not there.
