Storing only encrypted source in the source control system prevents
your system administrators from being able to read the source. I
can see value in that. The problem with multiple consumers of the
same encrypted data is already addressed by PGP. I don't see any
reason why this can't be done; after some thought, the idea of
doing it in a wrapper around your svn tool probably won't work well
for some operations, like svn diff especially, but there's no
reason the svn clients couldn't understand that some source files
are encrypted and, when creating a diff, decrypt the pertinent
versions and then present a diff of the cleartext. Obviously diffs
of cyphertext are of limited value.
