That's exactly what I am doing here.

I keep all the "common" files in trunk, and I have a branch for every
customer, which contains the files from trunk plus the customer-specific
  extension.

I have a lot of duplicate files (every file from trunk is duplicated in
every branch), but as this are "cheap copies", this doesn't hurt too
much. OTOH, this has the advantage of having the possibility to change a
common file in a branch, test it in the customer environment, and decide
if the change should be backportet to trunk (and in a 2nd step to every
branch).

SOmetimes I decide that a customer-specific file should no longer
customer-specific but common, so I simply copy it to trunk. Sometimes I
decide it has to be the other way round (a former common file becomes
customer-specific): I simply delete it from trunk.

To maintain all this stuff, I wrote several scripts that compare the
common files from trunk with all branches, and suggests diffs and/or
merges (based on 'svn diff --summarize')

One drawback is that every change to trunk results in a diff for every
branch (and I got about 20 branches), so the commits (and the repository
itself) becomes quite big. A proper solution would be a "svn replace"
instead of a "svn merge", but I couldn't find the time to improve my
scripts to to this (apart from the fact that there is no "svn replace"
command)

HTH, Michael
