I guess ideally people subscribed to this list want all exploits to be stopped 
:) But seriously I don't have any preference at least for now. Since I will 
have to learn a lot in this area I want to start from something which would be 
a reasonable and useful for this project piece of work, that's why I was 
asking for suggestions.

reasonable ready or researched enough for sensible questions/discussion 
points. I will be away for long holidays until Jan 10, but hoping to return 
with plenty of energy :)

Merry Christmas and Happy New Year to everyone!
