Before a full blown proposal suitable for a vote I think there are quite
a few detaiuls to work out, like:
- making sure the svn:externals actually work as expected in the ASF setup
- which mailing list(s) gets commits messages for the various directories
- getting some input from other stakeholders like Pluto guys or Cocoon
portal guys (possibly Geronimo) about the optimal directory breakdown
- figure out a build system that actually works on such a beast

and then vote and implement the proposal.
Maybe we could start a poropsal draft on the wiki to start formalizing a
precise proposal while the discussion goes on.

I don't know if build goals are really the best tool to "configure"
As far as I understand the situation, different "jetspeed packages"
could possibly vary from one to another based on:
- the spring assembly files used (that would control the portal features
  and select appropriate component implementations for the target
- the portal applications bundled within the package
- the bundled runtime environment (defaults users, permissions, themes
and pages)

IMO, some of these choices should be made at the source repository level
(like assembly files), some at compile time (maybe runtime app server
target) and some at runtime (choosing which apps to deploy or choosing
whther to create default user environment or not ?)

Having only build goals to manage this complexity will probably lead
to issues later with an exponentional number of possible combinations.

If we go with svn:externals as proposed above, it could be possible to
link diferrent config dirs to handle the source repository level

Cool, I will have to try it one of these days... :)
