ok lets move past the what if.   or could be.   I have read most of the
threads since the inception.  Who is the moderator or top level person for
security for gentoo.   Have they posted or addressed this on this thread or
in general?   that part I was unable to find?

I dont mean to simplify or over complicate the matter.    But is there a
legitamate solution or proposal on the table.   I have read some great
ideas,  and some very dis-heartening ones as well.    Like most of you I
love gentoo,  I love the concept behind it.   So now lets move toward a
solution.    There will be flaws with any of these ideas,   but there has to
be a solution that will be a bit more secure and resolve some of the issue
at hand.   wether that is PGP or .jar or  DSA keys.
