I am sure you already know how you are going to do this, but in my
[bundles-lib]([https://github.com/palindromicity/bundles)] I support this for
manual cases ( like installing from a ui ).
The way I did it was to make the InitialContext classes represent an
operational context ( IE> I am building the context on demand for a whole
directory like at start up or I am building it for a single NAR ), and to
support merging contexts.
I look forward to seeing what you come up with.
