Definitely.  I think its good to have a diverse Pd ecosystem.  I want  
to support that. The big disadvantage is incompatibilities.  So when  
its easy like in this example, then we should do the bit of work to be  
compatible.  The dirlib approach so far seems like a simple subset of  
the libdir approach, so that's a good thing.  If people who use  
dirlibs just stick a 'mylib-meta.pd' file in it, then people can  
choose between the two approaches without changing anything.

Of course, libs depending on libs is harder question.  I think we can  
make it work for both the dirlib and libdir approach.  This is how I  
see it working:

myproject-\
                    |-rjlib
                    |-mapping
                    |-purepd

Then it should be possible for objects in myproject/mapping to find  
objects in myproject/purepd.  Currently, there seems to be some issues  
with that.  If anyone can think of any, please add it to the relevant  
wiki pages here:

http://puredata.info/dev

Then we can use them when implementing the library ideas as discussed  
at the last PdCon.
