about thunderbird patch...

Does anyone subscribe to the thunderbird dev list?  

Would someone be interested in subscribing and seeing if they can drum up
interest in helping with the thunderbird part of the plumbing to put
hashcash suppport into thunderbird?  (Or create a patch to do that).

Presumably this could be done via hashcash library, or just direct - its
fairly simple given access to a SHA1 library, key value store (like berkely
db etc), and mail parsing library that thunderbird will have.  Seems like
most ingredients are already in thunderbird.
