This is what most existing frameworks such as COM do fwiw. Another
convention is to put "X" in there, like "XPlayer" or "javax."

Java typically creates a new package with a new API for major changes,
e.g. io -> nio

Well, just because the Linux world seems to be kind of retarded about
this. Lots of pushback on ometer.com/parallel.html too, for "aesthetic"
reasons. I think the Java and Windows worlds both "get it" on this
front.

People are pretty sucky at bumping library sonames too... openssl,
libpng, etc. all historically screwed up. And libdbus for that
matter ;-) though we are pre-1.0.
