Nice work! This will save folks a lot of time!

Is there anyway to have it pull down the most recent JVB?
Right now it's:
wget http://download.jitsi.org/jitsi-videobridge/linux/jitsi-videobridge-linux-x64-101.zip
Incidentally, I rename the jitsi-videobridge-linux-x64-101 directory just to something like jitsivideo so you don't have to updated the /etc/rc.local directory with every JVB update.

Personally, I like to use a more recent version of nginx since Ubuntu 14.04 seems to have nginx 1.4.6, but that's only from March 2014.
You can get more recent nginx by reviewing this:
http://nginx.org/en/linux_packages.html#stable

Also, config.js has desktopSharing: 'ext', but you should consider change that to webRTC in light of my recent discovery:
http://lists.jitsi.org/pipermail/dev/2014-May/020880.html

I prefer my nginx site configurations to go in /etc/nginx/conf.d/ and you have yours going to sites-available.

I agree with lots of your points. The script can be easily improved. For the most recent JVB, I don't really as for now. If I don't rename the JVB to a "standard" name is to be keep tracking of what version have we installed. In both case it's not a big deal.

Nginx: repos are so less troublesome I will think about change that.

Yes the installation of Jitsi meet is a little too standard, especially about the desktop sharing.

Nice work!

Unfortunately the newest version will require jicofo https://github.com/jitsi/jicofo

Unfortunately the given script will not configure nor install the focus server (jicofo). I just wanted to add this for everybody who uses it.
