Re: GSoC: collaborative editing

[Richard M Stallman]

    A peer-to-peer approach has advantages, of course, but it also makes it
    very difficult to recover a total ordering and hence guarantee that
    every client sees the same content.

Yes, but it should be possible to set it up so that conflicts are
reported.  They will only happen when two people edit the same area
in a short period, and that is asking for trouble anyway.

It is very important to promote peer-to-peer methods of doing various
collaborative tasks, because servers cause issues of control vs
freedom, and peer-to-peer is the only way to avoid them.
