John, I do know the matter, and I even chatted with Ben and others
before issueing it. Ben said that at one point he will create a
meta-issue to collect these ideas.

Uh? My proposal simply add a new place to look for settings, that is
look also in './.subversion' after '~/.subversion'. The suggested
approach has several advantages over a per-repository new conf/
setting.

The proposal is an /alternative/ to having such repos-wide settings.

In fact, this is why I think my idea is much simpler and as effective
as the repos-wide one, without requiring additional code to transfer
to/from the server another config file.

No, each directory could contain its own .subversion folder, and the
developers are free to put it under revision control or not.

No, *each* subdirectory of a repository may contain the .subversion
settings folder, that applies on the containing directory and its
subtree. This way you can get different policies in different part of
the repository. For example, mine have a '/3rd/' tree that contains
external software synced tipically with some sourceforge.net CVS
repository: for obvious reasons, I do not want SVN properties be
active there and below, while it would be nice if in the other trees
(say, '/mine/trunk') I could activate auto-props.

Ya, of course. That's the main reasoning behind making an issue out
of it.

thanx,
bye, lele.
