Another workshop i'd be really interested in running would be one on information and intelligence gathering using a program called Maltego.
Maltego is a really cool app that can search a huge range of sources for whoever or whatever you're looking for and display the links between that information visually. Its kinda hard to explain, you really need to try it to understand what it does, but the description from the website helps a little:
Maltego is a program that can be used to determine the relationships and real world links between:
* Groups of people (social networks)
* Web sites
* Internet infrastructure such as:
o DNS names
o IP addresses
* Documents and files
If anyone's interested the site is at: http://www.paterva.com/web2/maltego/maltego-2.html
Ignore Maltego V2, as its the newly released commercial version and costs big £££, its the open-source JS1 release you'll want.
To get a better idea of how it looks there's a couple of screenshots here:

...and a couple of videos here:
I'd imagine many activists would be quite interested in this, although it should be useful to anyone doing any sort of research. Frankly its pretty easy for anyone to get sucked in and waste many many hours just playing with it, as i've done many times in the past
I think an intro to this could easily be done in a 2 hour evening session if anyone thinks people might be interested...
