Sorry, my numbers are way off. We were paid: 1 hour for every 8 hours with the pager that we were not already working so it added up to: 3 hrs per weekend day, and 2 hrs per day during the week, for a total of 16 hours per week for holding the pager, 17 hours on holidays:-)
Worked as a software dev for a large banking firm in Canada. We were paid four hours a week just to hold the pager, and then time and a half for any calls we received, with 30 min automatically charged as soon as the pager rang. We couldn't travel out of the city when we had the pager, and had to limit drinking to meals.
Why a net? There's no resistance in space and no medium that needs to pass through the net!
Make it a big metal cup like the back of a dump truck. Drawback would be increased payload for launch, but it helps remove a lot of the risks others are describing such as the net breaking or contents of the net breaking up into smaller pieces.
