Yes, use svnmerge.py to set up merging in either direction.


We use it at work for per-developer branches and it works great.

You set up svnmerge.py on the branch and on the trunk and with the -b command
line option, if you only use svnmerge.py to do your merges, then svnmerge.py
will not merge changes from your branch back into the trunk the originated from
the trunk.
