My personal experiences using prototype on the FE didn't gave us any 
problems.

Fairly, however prototype and scripto.... might be important enough to 
change our code if possible.
They contain quite a number of really userfull functions not to be 
quickly overlooked.

I didn't see Peters warning, I did see problems on the net... However 
quite a number of people
like to bitch about others software in any case...

Search for '<anylibrary> and conflict'. I think mostly libraries will 
conflict with some
other library. The question is can we adapt our library towards something
we want to be compatible with?
