Hi Dave,
The original 20 ICT ideas in 20 minutes was for internal staff training. The concept was to get as many staff as possible to put together a one minute presentation sharing how they had implemented an effective use of ICT within their classroom. It served its purpose brilliantly as the whole staff could see 'normal' staff rather than ICT geeky ones (i.e. me) sharing ICT ideas.
However, since then I have delivered training sessions - 40 ICT ideas in 40 minutes, 20 ICT ideas in 10 minutes and this - 30 ICT ideas in 30 minutes. The focus on these has been the same topic - suggestions that others can take away and develop further - but the delivery has been different - I've done them myself.
The original training was much more about the process - each member of staff was asked to write up their thoughts and ideas about the ICT idea and the benefits for their subject. Whilst I had to fill in a few gaps, the majority of staff did a fantastic job with this and we produced the accompanying booklet. For the subsequent sessions I focused instead on what was effectively:

"There is such a wide range of fantastic stuff out there - here is a quick glimpse of some ideas, please explore further if you are interested"
So, in answer to your questions:
1. The 30 ICT ideas - delivered to a small group of under 10 Maths & Computing Specialist School coordinators. Here the aim was to illustrate what we'd done in the past and share some ideas for them to take back and enthuse their staff
2. Completely mixed - this was aimed at staff who were ICT capable, but perhaps not entirely confident
3. I was given 30 minutes for the presentation - so it was precisely 1 minute per idea.
4. I used the slide as the basis but then explained why I felt this idea was useful, how it could be useful within schools together with any benefits / issues to be aware of. Trying to ground each idea in an example of how it had been / could be used within school was the key thing.
5. Extra information was available in the form of the ability to contact me, contact the school - but really this was about whetting individuals' appetites so they would come to this forum, get involved in Twitter and - at the most basic level - Google any ideas that they liked the sound of to develop further.
Perhaps not exactly what you are after but that is how I used this one.
Also, I am delivering another '40 ICT ideas in 40 minutes' at this summer's Maths and Computing conference. I have a few ideas how to make this more than just me talking to people though. I'll put some proposals together but I'd love to make it a collaborative training session....
