Wow, this is a good idea, although i suggest a dagger(or something) to go with it that if used can cut through netting after about 5 seconds. And the dagger could also be used as a weapon.
*off topic..kinda*
Also, it would be cool if someone made a net "brick" or object that can be placed via net cannon for blockland to either set traps with or land in from high places and not die.
