Sure I'll give it a shot.  I'm not too fimiliar with the codebase 
especially anything twisted related.  I would like to setup the testing 
so I can do things like create fake svn commits are there any docs on 
that, currently I use actual svn commits which fills up the logs with 
lots of 'testing' commits.  Up till now I have had only a user 
experience with buildbot and made some minor mods to suit my needs.

I will start some work on this and see where it goes.

1.  I am guessing that the try scheduler can accept a patch and that I 
might be able to port this over to the force scheduler?
2.  I'm not at all sure how I'm going to be secure on the contents of a 
patch, or the result of it.  One of my reasons for using the force 
scheduler is that I can then only enable the patch functionality to be 
applied through an authenticated user, whom presumably I trust.
3.  A  command line try client separated from buildbot and it's 
dependencies sounds good, but I think not a necessity to get this working.
4.  JSON input would be something I would also put in the 'would like to 
have' basket.
5.  Unit tests, yes just have to find out how to create them for buildbot
6.  Docs, of course I love doing documentation (Just in case your mail 
client doesn't show it that last bit was written using the 'sarcastic
