Bingo! I seek to propose a hook that would essentially allow the role
system to become dynamic.

Since my modified user_access currently works for
list/view/update/delete, the menu system works perfectly. The correct
create content links to add the correct node types for a role appear as
they should. The problem is when I click on node/add/<node
type>?gids=<group nid>, the user gets "access denied". user_access
returns the correct roles, but there is something else in the node/add
process that causes this process to fail. My guess right now is that
$user->roles is called somewhere else in the process (outside of where
it's called in user_access), and that's causing the failure.
Problem is, I just can't locate where this is.

I understand, and appreciate your response. OG dynamically rebuilds
it's menu each time, so the overhead would be the same. And, again, the
OG menu uses my modified user_access to build the correct menu according
to group role(s).
