I just pinged support on this over the weekend. Here is the response:
Thanks for getting in touch.
We don’t officially support automated blinds right now, but there seem to be a few options (including that of the MIMOlite you mentioned).
Check this out:

I’d also recommend you post on our forums at http://community.smartthings.com and see what other users are doing.
Thanks!
