Perhaps audiomath/libaudiomath.so makes the most sense so that it
can't be loaded by Pd as an objectclass. But I am guessing.

I like having each objectclass as its own file. Then only the code
that is in use will be loaded into memory. linking everything
together into one zexy.pd_linux means the whole thing is loaded into
memory, no?

I am sure you don't mean to do this on GNU/Linux, right?
I take it you mean like including a .dylib in the Gem folder? Kind of
like what I do with Pd-extended and the Fink dylibs? That is not a
great system. I think due to the limitations of the Mac OS X shared
lib loading, it would be painful. Basically, AFAIK, a .dylib in Mac
OS X must have its path hard-coded in the file. Otherwise, you have
to load it manually with a direct call to dlopen. I don't remember
the details in Windows, I think that it already checks "." for .dlls
by default.
