Re: Is there any effort or discussion yet about collaborative use of libreoffice applications?

Hi Marc,

	A few thoughts on this thread:

	This is a development mailing list; it is great to ask questions around
the code. There are two approaches to Collaboration as you've seen the
COOL approach (poke in #cool-dev on IRC), and the Telepathy approach
that Caolan kindly pointed to below inside LibreOffice.

	The telepathy prototype is no longer included - but the patch Caolan
pointed at has an attempt to pull out a set of 'operations' that might
work for spreadsheets, and could be built on. I expect some of the core
re-factoring to make this easier is still present.

	This mailing list is a great for developers to discuss resurrecting and
extending that - it's a generally useful feature - although it is really
far from trivial to implement, even with the synchronous event model
that was imagined and integral to the Telepathy attempt.

	Personally I'd recommend trying instead to make LOK more deterministic,
and doing this at the LOK user / input event layer: but even that is
rather tricky - consider a sort of some data via a column populated with
=RAND() as a banal example - and needing to synchronize that across
multiple users.

	Anyhow - I'm happy to help with any code suggestions / reviews as/when
you have a core build and are ready to go there. I would recommend reading:

https://people.gnome.org/~michael/data/2013-10-09-collaboration.pdf

	first for some more background. We chose to go a different route with
Collabora Online - which should be much easier - but like anything
complex in practice is really hard to get right too =)

	HTH,

		Michael.
