For the same bid as the previous message the client also wants to track matching donations.  This would require relating contributions to pledges which AFAIK doesn't yet exist.  Here's my thoughts on workflow:

• An organization agrees to match contributions based on some criteria (time frame etc.). 
• A “matching pledge” object is created for the organization with fields for criteria (time start, time end, amount min, amount max). 
• Several contributions are recorded to various contacts that match the criteria.  If they match the criteria they are recorded as a match.
• Once the time frame has ended all matching contributions are totalled and the organization makes one contribution.

I think this could be done as an independent module, only using the post hook to integrate with contributions.  Or is there more required here.  What might this take to build as far as actual components and the time required?
