Waiting for new standards you never know how long you're going to wait. Hardwiring is going to be best but obviously not a solution for tablets.
I suspect (but those with more knowledge, please chip in!) that multicast to unicast conversion (sending via unicast to those stations the AP has seen relevant membership
reports from) on the access point may be the domain of higher-end commercial
kit but I did google
some discussions from late last year about adding the facility to OpenWRT. Anyone involved with that got more info (or know of other affordable access points/routers it's a possibility on)?
The easy option might be an access point which allows setting of multicast rate, cranking it up and maybe reducing DTIM interval at the expense of tablet battery
life. Do the apple airports have that facility, or anything else without a "commercial" price
tag that forum members are aware of?
A quick look at the BR24 plugin code suggests that the way it is written it will accept data sent to the correct UDP port on any address the system is listening on (i.e. not only the intended multicast group). That does offer the possibility of translating multicast to unicast elsewhere off the wireless network and firing it at the computer running OCPN. Easy enough to do with socat on a linux
system (or open source router) if you have a fixed address for your computer but frankly a bit of a faff if you have to set it up manually. You'd also need to prevent multicast from being propagated to wireless.
Maybe what you need here is a large group of relatively tech-savvy boaters with a wide range of networking solutions on their boats that could fiddle with settings on their access points and report back via some, oh I don't know, international Internet
forum or something, about what works for radar-over-wireless.....
