[Sugar-devel] [ANNOUNCE] Groupthink 0.1 pre-alpha

[Tomeu Vizoso]

Hi Ben,

can we use this on non-sugar pygtk apps?

For example, could we use it to add collaboration features to
Labyrinth (a pygtk app that we are reusing as a Sugar activity)? Or
does it depend on Sugar in any way?

If the data model supported sharing through telepathy tubes, I think
that the upstream GNOME developers would be interested in helping us
maintain this code.

Regards,

Tomeu
