+1, though this raises a few questions, look below

yes, and this opens up other issues (admittedly a wider scope then
applicable to current disc)....such as packaging with such deployment
reuse structures...is there any XML digsig component of what we are
discussing?  I think a bit of research is required to review some
existing packaging efforts with XML, did this about a year ago, there
are some interesting things happening with respect to compound xml
documents, archives, packaged components

should a compiled module come along with any meta data that maybe
introspected (version, author, etc)

is there any XML DigSig relevence with respect to protection, checksum...

any alignment with popular deployment package formats e.g. war/jar/ear

etc, etc...
