Arm bonds: Probably 4 or 5 people to apply, removal time (and maybe even tools required to remove, especially if there were locked handcuffs that had to be broken if you didn't have the key as an option) dependant on type of bonds (rope type, leather bands, metal cuffs). While bound this way, the bonds would appear on the description and the person would be unable to attack, point, or work on projects. Maybe also unable to give items to people or add them to projects.
Leg bonds: 4-5 people to apply, removal time as for arm bonds. Bonds in description, and character cannot go onto roads or enter and exit buildings. If it were possible to apply them on a road, the character would be unable to move at more than 0%, but that's probably a bad idea.
I've been thinking a little bit...

Of course, quite probably either this is seriously unimplementable or there's already a mechanism in the works for tieing people up.
