If you encrypt a given blob with AES, you will be able to decrypt it with any 
other AES implementation. Everything else is a bug in one of the AES 
implementations. No need there to worry about backwards compat.

Re: encrypting koffice files: Just wait for the XML-encryption framework to 
stableize and use that. XML-sig is already Candidate(?) Rec. No need to worry 
for backwards compat here, too.

I haven't looked deeply at XML-sig, but it seems to be independent of the 
backend used. So you could even let the user choose whether she wants to use 
PGP, X.509-based or symmetric encryption ;-)
