A couple questions just to get a better idea what you want it to do, and to spark new thoughts from HF members.
Do you want it to envelope the whole hammock, from suspension to suspension? If so, it could hang from a "Single Line Tarp support", even when you didn't use a tarp.
Not only could it be used with out the tarp but it could also be used with out the hammock too (lunch break, etc).
When it's around the hammock, do you want it to go to ground so all gear is enclosed?
