Updates with bsdiff (was Re: [DISCUSS][PROPOSAL] redirection of update services to www.openoffice.org)

[Pedro Giffuni <pf...@apache.org>]

Hi,

This is somewhat off topic so I changed the top
subject.

The one time I updated OpenOffice it took a long
time so I am under the impression that we are
doing the really dumb thing of downloading all
the office suite again.

At least for security updates, which are rather small,
I think we should consider bsdiff:

Also note that Google Chrome developed Courgette:

http://dev.chromium.org/developers/design-documents/software-updates-courgette

and while it's better and it's openly available, they
were sued for patent infringement!

Pedro.
