	All the above taken into consideration, with careful configuration LibVNC works in ZM, and it does a good job. It is a powerful tool, if you want to keep tabs on an organization~~. You~~ can monitor activities of your employees and get a deeper insight into a business' workings. Or if you have kids, you can monitor their screen usage.

			===Sync Issues===
			I have found LibVNC sync issues where the computer can get a frozen screen, so I recommend restarting ZM at the beginning of each workday. todo: write an API call here to restart only the VNC monitor in crontab.

			===Recommended Way to Watch Videos===
			I personally use this script to make a daily MP4 of all recordings, and I can say that it does a much better job than watching through the web browser interface. More efficient. Highly recommended.
