Buildtime: no.  We create a hash of current pathnames to desired pathnames relative to the jar archive and package efficiently (directly).

Runtime:  dependent on the JVM implementation that hosts the Bear.

ASDF-JAR includes both source and fasts by default.  The ABCL
compiler should always be available, but it can take a while before
the JIT really warms up, so binary fasts are desired.  That Java
has a universal byte code representation is used to great advantage

The assumption is that the additional bytes to include source is

GAE should be able to use binary artifacts produced by ASDF-JAR without issues.  [abcl-servlet][] provides a plausible hosting framework.

We love features.  It gets us more users.
