That sounds like the optimum solution. I've been reluctant to come
up with this in the first place due to lack of time (as I have
to keep my focus on developing firmware for the FX3). I doubt I 
won't be able to go for it in the foreseeable future, as long as
the simple approach works.

One thing that might changes necessary however is the new
firmware format that Cypress talks about in its FX3 API 1.2
release notes:

http://www.cypress.com/?docID=38763 

With prior versions, the FX3 had to be reset by an on-board
switch or un-/replugging the power supply. Now the firmware
should allow a reset while the device is connected (p. 6 of the
manual). 

Still, right now it's still unclear how such a reset is going
to be initiated. I'll keep you updated.

All the best,
