1. For our conference guests we give then 1 username and 1 password for all their delegates. (this could be 50 to 100 people) We have a 30MB line and I would like to know how to limit the bandwidth say to 5mb Max per user (I don't mean that all 50 to 100 users only get 5mb) for that specific username and password. The 30mb should still be shared to all delegates.
Is this possible.
Easies way to do this is to use hotspot, two profiles one for conference guests and one for other guests. in each profile you can have bandwidth limit, burst rate etc. Hotspot will create simple queue for you when users logs in. so search for hotspot examples.
2. How to stop delegates from using the wifi for VPN's or restricting VPN bandwidth
Not sure you want to block VPN if there is conference. as long as they are with in the bandwidth limit, I don't see a problem if people want to use VPN. Anyway, you can block ports used by PPTP but SSTP use 443 so you cannot blocked it. Not sure whatelse you can do. someone else may know better.
3. How to stop delegates from downloading torrents etc.
OK, I have the same problem but there are Layer 7 rules . I find this one works for me

it blocks P2P traffic but this stops some games. for such users I suggest them to use VPN
I use it together with those method that checks torrent sites
