True, but what happens if the users need to use a previous revision?
This becomes impossible, as you have forced all versions of a particular
.DLL, etc. to be the latest, without retaining history of the previous

I, too, am not a subversion programmer, but I also belive that such a
property would cause more problems than it would solve. Have you thought
about setting up an external repository containing only the third party
software releases? This way the 'overwritten' files appear to be, well,
overwritten, but the version history remains.

An alternative solution, maybe, would be to allow for a purely
file-based 'externals' type property, that simply performs a file-system
copy from the source-location to the destination, rather than a SVN
checkout operation.

                \third-party -> svn:fs-externals =

I'm not advocating this solution over any other, just throwing it out
there as an idea.
