After my post yesterday, I managed to make it work and I must say that 
it works pretty fine.. and it will solve my problem.
If only a few of the decrypted files changed, the process is quite fast, 
and I think its a very good companion to rsync for incremental backups.
I think the fact that rsync still retains ability to see only the 
changes is a big plus point.

Yes I tried it on Linux after I went home yesterday and I take my comments back!

Piping the output file to rsync would be great as a future idea, but 
since encrypting all the files then doing an rsync probably takes more 
or less the same time as  doing them piped, it doesn't really affect my 
solution at the moment.

I think it would be nicer if some more verbosity is introduced (for 
example in the case of the src and dst being identical, write something 
to stdout, or at the end of encryption, to write 'n files encrypted' or 
something of that sort)... I might actually implement them for my 
solution.. maybe I can then help with the devel.
Also the same in case of errors (invalid certificate etc..) but if 
anything those go to the rsyncrypto list.
