I think we should try to find a way  to avoid nameclashes! Taking the above
example, someone might only be using the maxlib library and thus [gauss] is
perfectly allright. Let's say someone else is running Pd with footils library,
there one would get gauss from footils... Not what we want, I guess!

On the other hand, I think, it would be rather easy to implement a mechanism
that tell's pd from which library to load an object from when typing
[libraryname.objectname]. This could be used to force Pd to use gauss from
maxlib, not from footils in case both are present. But, right, this makes object
boxes much longer.

BTW, what does Pd right now if there are two identical objects? Does the one win
that is loaded into Pd first? (I gues the order is Pd core objects -> libraries
-> single externals -> abstractions ?)

We allready have a similar thing when specifying which library to load. I don't
see any differences here.

I think the best - and most difficult to implement - way would be to create
objects as usual but to save information about the libraries / namespace
(invisibly) in the pd patch. In case one of the libraries is missing on another
machine, one would get an error message instead of an object from a wrong
But then we still need a mechanism to force Pd to use a special library.
