Nice!
It would be extremely entertaining to click and watch any of my friends gameplay live.
and
It would be absolutely awesome being able by one click to stream a game I play to anyone interested.
There are programs and services that might help with this and it could be pretty easy to add this to Galaxy.
Plenty of other services have it already. To keep it safe measures has to be taken.
There is a spoon for a nice soup and there is a spoon for a desserts,
and these are two different spoons that user should not really mix to keep good taste.
Then again, let GOG grow freely for everyone. Two GOG`s teams.
Galaxy should have absolutely everything without having any effect on
offline installers, profile (sharing thoughts), drm-free games offered by GOG.com and internet browser stuff.
Then again, again, live streams within GOGGalaxy ? Yes!
