You should consider disallowing people to attach ropes to certain places.
May it be to avoid people shortcutting the map or using exploits, people being where they were not intended to be can have some nasty side effects (stuck).

Also you could have a config file with possible spawn points for ropes and maybe introduce it as an item.

Nonetheless I find the idea very interesting even though I hate gameplay modifications in general (I am a versus player).

Keep it up!
