I saw the projector, and keyboard, but not a DAC.

The Bluetooth DAC would be a BT receiver for the digital audio signal,
coupled to a DAC for conversion to analog, and then whatever else comes
after, such as an amp for headphones, or maybe a pre-amp for line level.

I can't speak to the latency issues Michael mentioned, and perhaps that's
improved with the newer Bluetooth audio stuff. When I was shopping for a
Bluetooth speaker, there were many acronyms being tossed around. :P

I was thinking something like this:

A lot of these BT audio DACs are targeted towards headphones, so you'd want
to be sure there's line-level audio out (which the ad copy might not say,
specifically, but "analog out" rather than "headphone jack" would be a
clue).
