[CDBUG-talk] Screen sharing options?

[Jaime]

I want to get a screen sharing service at my job for help-desk style
service.  I am looking for an open source product that I can host on a
server here, not something that is outsourced, due to a mix of
confidentiality regulations and a lack of funds.  Does anyone have
suggestions?

What I'm hoping to do is make a cross platform method for Mac,
Windows, and ChromeOS end users to share their screens to me when I'm
not in their building.  For example, my coworker is (as I type)
driving to another building just to stand in front of a PC and run a
program that the end users keep managing to somehow quit out of.  The
program allows a PIN number pad to work and its situated in an
elementary school cafeteria.  He is spending about 30 minutes to drive
to another building, run one program, and drive back.  What I'd prefer
is for him to be able to say (on the phone), "Now click on the Start
menu, now click on..." and get them running in 2 - 5 minutes instead.

Any thoughts?

Thanks,
Jaime
