Thanks for your support, but see my reply to Jeroen's reply to this message. 
The mirroring of the "edit" script can cause race conditions when two people 
try to edit the same page at the same time on different mirrors.

HTTPS authentication (the "tunelling" will be probably done, though). Do you 
have some knowledge on SSL authentication that you might want to share with
