Yes, I have wondered whether the USB external that Chipp has 
abandonded could be adjusted for a specific device like this. May be 
Chip should discuss this with them (I don't think they have a 
distributor in the US, so this may be a business opportunity).

I may not have said it clearly but the company actually tested that 
their device works fine with Rev using AppleScript. They say the 
syntax is like

   do "set SERVICE output value 85" as applescript

to set the output value to 01010101 binary, for example. For many 
control applications, using AppleScript can be just fine.

They are just looking into developing an example stack for Rev if 
there is enough interest.
