At a very high cost :-(

That's problematic. While the goals are quite clear, the steps to
achieve the goals are inpredictable in most cases - everything depends
on problems encountered during an implementation attempt. A discussion
of such problems requires some familiarity with the details, and with
the consequences of possible solutions. Too bad when obvious
consequences are not mentioned just-in-time, because some guru has no
time for following the discussion(s).
I'd appreciate better ways for providing material for discusson, than
branches in the SVN repository. Such branches are hard to remove, if
ever, and restarting with a preceding version, when a dead end was hit,
also is problematic. Currently I try to provide some patches, based on
SVN patches, but developed using a Git repo. I found no solution for the
different revisions, that are required as the base of both SVN and Git
patches - anybody?
Another solution could be a (non-tracking) Git repo on some public
server, where experimental branches can be created and removed freely.
Patches for inclusion into the SVN repo can be created from a Git repo,
when both share the same working copy. Thanks to Graeme for mentioning
this trick :-)
