I like the way the Blackbird I just got does it - the zipper is not on the bug net at all but a few inches into the fabric of the hammock. There's enough hammmock that leaving the bugnet open and out of the way doesn't affect laying in the hammock.

I have a silk hammock and will use some loose hanging gauzy material for a bug net - going to put pockets along the edges and velcro at the ends to seal them up.
