Double precision is no silver-bullet. Double precision Pd needs more 
memory and can run slower on certain platforms (for several reasons).

Pd patches are not affected, they are just text files. It's really only 
about existing externals. Once you have your externals compiled for 
double precision, existing projects will work.
