apogee one with apogee duet

[m.e.d.]

Does anyone know if it's possible to use both the apogee one with the apogee duet? I wouldn't buy these products specifically to get a 3-track recording setup, but as I'm considering buying a 'one' for its built-in mic, and I already have a duet, I'm curious if anyone has tried to use them simultaneously.

Ya know, I could use a third channel. Just last night I needed that one extra channel going to really get what I was after on an acoustic performance.
I'm not sure if having both recording at the same time will work or not since you'd have to assign one of them for your audio in/out. ????
