        Normally, a revision number by itself isn't enough to identify
code. You need the path/url also. (If you have no branches whatsoever,
then the rev number would be enough.) If you need both the svn_url and
rev_num to identify a baseline, then there's no difference in the way
you reference a meta-repository or multiple repositories, so creating a
hack to have a single revision number across repositories would be would
be largely meaningless.

        Filtering might work. In theory, do 999,999 commits and do some
filtering.

min.maint.filtering
        And then use "--drop-empty-revs Do not generate empty revisions
at all-just omit them." No idea if it would preserve the rev num would
be at 100,000 when done.

What's the rationale behind having a meta-revision number? There might
be a better to achieve your goal while still fitting in with Svn's
paradigm(s).
