1) You need an explicit example of what virtual/jdk/jdk-1.4.ebuild looks
like.

2) For the consistency section, I'm not sure how you're going to
implement this. The example I tend to use is this (versions simplified
slightly for clarity):

* User emerges vim-6.3, gvim-6.3. ~vim-core-6.3 is in as an RDEPEND.
* User upgrades to vim-7.0. ~vim-7.0 is in as an RDEPEND.
* User still has gvim-6.3 installed. gvim-6.3 has an RDEPEND upon
~vim-6.3, which is no longer installed. gvim is now broken.

An example of exactly how portage would 'solve' this would be
helpful. Would it ask for an unmerge of gvim-6.3 or would it include an
upgrade of gvim-6.3 as part of the "emerge ~vim-7"?

3) We don't specify every virtual in every profile thanks to cascades.

4) Backwards compatibility -- all virtuals ebuilds should include
DEPEND=">=portage-2.whatever" as well as the "|| ( foo bar )" stuff.

5) Someone tie up TGL and don't let him escape until he agrees to be a
dev this time.
