You need root access to install BigBluebutton. If you have a hosting account that only gives you, for example, FTP access and a cPanel interface, you will not be able to install BigBlueButton. There are a number of OpenSourceComponents in BigBlueButton that need root access for installation. These include Asterisk and nginx. The former provides to voice conferencing, while the later provides the proxy server for enabling clients to use BigBlueButton behind a firewall.
Hi, I prefer to also use Hostkey, but the price you mentioned seems a little too big to me, especially the place of origin somewhere in an unknown place, I use this in the territory of the states, everything functions instantly and a lot of nice functions!
