I'd definitely like to collaborate on building a Blunt 2 compatible
module. I haven't heard from Eckhart yet though. Does anyone out
there in list-land know a good address for him? I just emailed his
support_at_40hz.org address, which means my message is probably lost in
a sea of Blunt support requests...

Class 1 Bluetooth v1.2 I believe.

The antenna is internal. You can see it in the picture sticking out
from the board a bit. It works to my computer a few feet away, but I
haven't tried any tests

Again, not tested. Specs say 2mA in idle. There's a "deep sleep
mode" that draws only 90uA, but I'd need another pin to "wake up" the
module after. Right now, I use the one and only extra GPIO pin on
the internal connector for "reset" (you have to reset the module or
it won't work after power up.)

No LEDs (there's nothing outside the newt to see, even if it had one)

I don't have an eMate, and I don't know if the eMate has an internal
modem slot like the MP2x00
