I have not tested yet what happens with local changes after the block is "mounted" using svn:external. Any experiences?
I've been using svn:external for including the documentation in the simile.mit.edu web site (which is managed in SVN) importing the /docs that come from the various projects (so no code) but I have no found a problem yet with this approach.
The only problem is that 'svn status' might not show you changed done in the imported blocks, you have to 'cd' into the block directory and do 'svn status' there.
[but there might be a switch somewhere in turn that behavior off... that havn't bugged me enough to be concerned about it]
