Putting ACL's on the developer content is completely counter
productive in an open source project IMHO.

Why are you trying to make it more difficult for people who are 
interested in hacking gentoo (and hopefully contributing back) to
do so.

All content should be readable by anyone (and even editable if you
are really planning on running a true wiki).

Let people read the content.  

Let them do with it what they wish with it.

Putting restrictions will just curb the growth of the Gentoo
developer community with no real benefit.

If you want to put ACL's on publishing to the GDN then that makes
sense, but not for reading and accessing.

Just my $0.02
