Hmmm ... that depth would have to be user-settable, right? So either
the keyword includes the target to use

        $SvnRevision:../../..:$ non-expanded
        $SvnRevision:../../..:6329-9654$ expanded

or maybe the svn:keywords value that specifies to expand this one
would also name the target

        $SvnRevision$
        $SvnRevision: 6329-9654$

        svn pset svn:keywords SvnRevision:../../.. thatfile

Something along those lines?

I'm not sure it makes sense to me. More to the point, does it make
sense to the people who want this?

Suppose the file with the expandable keyword is "conf/revfile" (below
trunk/ or tags/whatever/ or branches/whatever/, as the case may be).
To build a release that includes one patch, the buildmeister does:

        cd trunk/ # or branches/whatever, or ....
        svn up -r 1234 # includes conf/revfile, so it gets 1234
        svn up -r 2345 src # excludes conf/revfile, so it doesn't change?

Now revfile says "1234", but svnversion on "." would say "1234:2345",
which I think is not what anyone would want.

Mmmm ... an excellent point I had not considered.
