I just read on their forum that they got 1x VPW working late last year, but I don't see anything about 4x. It's a start... Definitely something to keep an eye on.
...and I just looked at the code they have to support 1x VPW, and it has a message length limit of 12 bytes, including the CRC byte. That might be easy to change (just bump the "12" limit to "2000" and see what happens) but it might not (bad things could happen).
It's still pretty intriguing though, I'm sure the hardware they're using is more than capable of high speed and large messages. If someone takes care of the firmware I'll gladly add support for this thing in the app.
