Hi Brian,

the mail idea wont work well for sf.net hosted project as there is a sync delay 
between the developer cvs and the read only cvs. I was looking at

viewcvspoll.py seems to directl access the viewcvs mysql database :(
fakechange.py from the commit-hook looks good, but then one still has to handle 
the delay and I am not sure if they have twisted installed on the sf.net cvs 

Any other ideas? I wonder if something like this could work - checking out the 
ChangeLog every e.g. 30 minutes and testing if it has been changed.
