I'm in for when it's available standalone, including with/if a reasonable price increase. (As it hasn't been stated yet about if mini-PCI card is included with the A1200 version, or not that I'm aware of, plus whatever 'terminator'/breakout costs there may be.)
Unsure about A1200 version, as I'd have to pick up an A1200. If it was definite the standalone version was going to be available and could purchase the 'terminator' seperately, I'd likely go ahead and buy an A1200 and the PV, then convert it later to standalone.
If you're not aware, there's also some additional questions after we posted your IRC comments (not too surprisingly), you may or may not want to comment on:
