Hi, hedpe.
In looking through
http://www.svnforum.org/ I saw nothing that seemed directly to answer your question. I searched for
commit link, and you might have better luck seeing something relevant. You might even try posting there if you get nothing else on point here.
The little that I did read seemed to suggest that the property
svn:externals might be appropriate -- however, that discussion seemed to be comparing features in sourcesafe, so I don't know if that is applicable to your situation.
I'm guessing that you want an item to appear in more than one directory in your repository. There was some discussion in that forum about hard links, and I think you're talking about s{oft,ymbolic} links.
I looked briefly through Mike Mason's
Pragmatic Version Control, and saw nothing relevant there.
I don't get the impression that many folks here use subversion, at least judging from the lack of response so far.
I had a situation where links were involved in one of my repositories, but it looked like the final result I have is a number of copies, not links. So I may be looking at the answer you get to resolve that situation for me (fortunately, not critical at this time).
Keep us posted ... cheers, makyo
