I really hope I've resolved this issue with the update I'm working on. [...] so I'm hoping to have it out soon, but it most likely won't be ready until the weekend.

That's great news! I can certainly wait until the weekend.

Meanwhile I have another data point: tonight I test drove a BiliPro USB pedal, and found that it also exhibits a slight delay turning pages (compared to turning the page by tapping the screen), but it's noticeably faster than Bluetooth.

I also learned that USB keyboards /also/ disable the Android virtual keyboard, but at least I can disconnect the USB cable, type in an annotation, and reconnect the cable afterward. This is a pain, but it's faster than disabling, reenabling and re-pairing with Bluetooth.

Incidentally, after I ordered the BiliPro, I discovered that AirTurn has a wireless USB module, namely the AT-104. I've ordered one but haven't received it yet; I'll report back on that when I get it.
