We're looking for something that will do something like this Python project:

http://www.logilab.org/projects/constraint/project_view

Basically a time-based constraint+dependancy+interval scheduler to be 
used in a project management app.  Is there a similar beast written in 
Ruby already available?  An option we're considering is to port the 
Python app and open source it.  If one exists already but is only 
partially implemented perhaps we can collaborate.

TIA
