Is a project-specific change_source possible in our buildbot setup?

Hi,

I have a question regarding buildbot change sources in our asf-buildbot 
environment.

There is a problem e.g. in http://ci.apache.org/waterfall?show=aoo-win7 
that one can see a lot of changes to the whole repository that are 
outside of our tree. This is confusing, especially as the got_revision 
property is set to the latest revision in the whole repository whereas 
the interesting part (e.g. to reproduce a build problem etc,) is the 
last change to that part of the repository that is used for building a 
project specific snapshot.

In master.cfg there is a line c['change_source']=PBChangeSource() that 
seems to be responsible for doing it globally. My idea is to change our 
project specific buildbot config (openofficeorg.conf) so that the change 
source uses the PBChangeSource prefix option to filter out any changes 
outside of our tree. Now the questions are:
- would such a change to openofficeorg.conf impact the other projects 
negatively? Are the buildbots connected in such a way, that this could 
happen?
- the PBChangeSource() line in master.cfg needs a userid and password 
from a module private. Is it possible and allowed that project specific 
config files use this private module?

Or maybe there are better ideas on how to the change source for our 
project specific buildbots only see the changes to our part of the tree.
