Calc has some rudimentary collaboration support.
Currently this is enabled by the 'ENABLE_TELEPATHY' - however, there is no real reason why telepathy should be required as the implementation. In particular it should be possible to hack and develop the demo (local) bus - without needing telepathy installed.
As such - it would be great to:
* isolate telepathy conditionals inside tubes/
* ideally provide mostly abstract / virtual interfaces that are implemented both for telepathy and also a local trivial 'bus' transport.
* ensure that calc is always built with collaboration present - and enable that as an experimental option.
Hopefully that would help more people play with this, and of course development to progress here better.
adding LibreOffice developer list as CC to unresolved EasyHacks for better visibility.

Now that the Telepathy feature was removed, I think we can close this one.
