If I may be picky for a minute, SubWCRev does not reflect the repository
revision. It reflects the highest revision in the WC (or part of the WC)
you have asked it to crawl. If you have 2 independent projects in your
repo, using SubWCRev in each of their WCs will produce the last repo
revision that a commit was made for that whole project, not necessarily
HEAD.

Provided the tree you ask it to crawl contains all dependencies as well,
you will get the repo version required to rebuild the same WC.

It falls down if you are using svn:externals, but there is nothing that
can be done about that, as externals can come from a different repo
entirely. Your 'about' box would have to list different revisions for
each external chunk, as TSVN's does.
