[Gmecm] ALDL for Android?

Assuming (!) the Android device (phone, tablet, whatever) has a USB host 
port, *and* you can add a driver for it that will enumerate a specific 
USB device, one may be able to homebrew an ALDL adapter.  Various micros 
(i.e. PIC) implement a USB device port, and a serial port, so a custom 
bridge that speaks the right bitrate over serial (and possibly knows a 
bit of the protocol) shouldn't be too bad.

Anyone have any Atmel or PIC micro stuff laying around that talks 8192 
or 160bps ALDL?

Sounds complex but may be the easiest to implement because it uses 
off-the-shelf hardware rather than homebrew hardware.

This screams for a dev. board of some small micro.  Beagle Board comes 
to mind but I don't have one so I don't know if it has everything one 
would need.
