njs ... great contribution. Looks like someone developed this idea and made it work. Brilliant! I've got to check this out. It'll probably turn out to be cost-prohibitive :-(
But New England Ropes is a very good company, so their product should be good. I emailed them to get a retail price - I'm mostly just curious (not sure I would really purchase it right now). I'll post if I get a reply.
