Comments: 

Just minor comments from remote observers: when I am in a different tab than keeper, apparently it disconnects after 1min or so and when I come back, I have to re-connect (2 seconds, nothing). Sometimes, we detected some 3-5s delay when using keeper, which is specially relevant when trying to check the last images (ds9, etc).
