What I had in mind was not the protocol part, but rather all the
surrounding stuff that needs to go into a special-purpose USB driver:
USB recognition, possible -x options, error handling, Makefile magic,
etc. Since you did all of that recently, you probably have a fresh
memory of all that needs to be done. I haven't had time to read
Eric's patch, but once it is working (on his hardware), implements a
reasonable set of features (power monitoring and shutdown), and is
reasonably NUT compliant, it should certainly be included in SVN. 

Before we make a release, you (for the megatec_usb driver) should also
think about whether to mark the driver as "experimental" (see
docs/new-drivers.txt:95). If you feel it is stable enough, it doesn't
need to be marked experimental. However, once it's in a release, there
will be a certain expectation that it works, and marking it
experimental for a while is a way to remind users that they are using
it at their own risk. 

The same goes for the Sweex driver when it's included.
