Thanks for the great summary. Sounds like iBlinds did some good things, glad to hear it.
Can we assume the 3.1 iBlinds driver takes advantage of the FW\communication improvements? NVM...I saw your comments in your driver thread...man, pretty disappointing that the iBlinds 3.1 driver doesn't take advantage of the status communication improvements in the FW. "Two Different Teams" syndrome... We had that sometimes at my old workplace...FW team develops cool innovation. SW team not informed, or mis-informed/partially informed, or just too buysy doing other stuff and SW isn't updated to take advantage of new FW. 
I'm off to look say your driver, thanks for sharing it! Update: LOVE your driver and the updates you've put into it. Will be using it going forward. Thanks again for your contribution(s) to the community. Five stars.
