I will be hosting a Ruby on Rails workshop at a small hotel in the near future, and while they have 'Wifi' everywhere on the property, and the property normally hosts 150 - 300 people, I am not 100% confident that they have hosted 150 tech people that tend to have heavy web surfing habits/needs.

Their tech department is also 1 or 2 guys.

Are there any automated tests I can download and run from my laptop, on the network, that would simulate 100 'heavy users' on the network at the same time?

Their broadband pipe is a 15mbps cable connection. Would that suffice for the general surfing needs of 100 - 150 techies? I know all it takes is 1 or 2 bit torrenters to kill the entire network, but assuming we can at the very least block those ports or encourage the attendees not to file share on the network, would that speed suffice for general surfing needs?

What are good resources online that would allow me to quickly get up to speed on the IT related issues, so that I can ask their sysadmins the right questions?

Edit: Note that I am fairly technical, so assume I can get up to speed quickly even with technical manuals, etc.
