Hi Allan,
Using the shutter to select good/bad times of seeing/wind was discussed as far as back as 2006 and implemented by Steve Bell around 2009.
IIRC it doesn't really work very well (minor improvement sometimes) as compared to lucky imaging where the improvement can be substantial if the exposure is short enough (milliseconds). Of course the read noise at such short exposures is a real bummer and a 'zero cam' is required
If you have access to the SBIG yahoo groups archive here are some references:

If you can't access them I could possibly copy/paste the text...if that's allowed?
