I'm not really sure what you are suggesting I do exactly. What do you 
think ought to be done and where?

How much effort do you think it will take? Like everyone else I don't 
have enormous amounts of time for projects I wasn't expecting.

Assuming it isn't a big task I am certainly interested in getting it 
done right. Whatever that is, hopefully it does include the same target 
working the same on all hosts (or at least all the same features 
working, for some definition of 'work').
