[PD] nameclashes

I have a hard time myself with the library thing...I usually use only 
one or two objects from a library. Would it not be preferable to have 
the individual objects from a library inside their own folder nested 
inside the externs folder?
I would also feel a lot better if there was a mechanism to register 
every object with a unique name, so that a developer who wanted to 
publish their object would register it in the database the same way you 
choose an email address: if the name is already in use, try again with 
another name. The names database could reside within the cvs repository.
So you would have counter, counter1, counter2, ...
