I am still working on pyzeliard, you can climb on ropes now. See the ropez.py (z from height) and other implementation files (ropeimp and base classes and such.)

There's also preliminary elliptic ropes code inside. The meaning of this is to hang on ropes such as e.g. in Indiana Jones movies or other jungle bridges.

The tarballs are at http://sf.net/projects/pyzeliard
