Unfortunately I'm not really close to the education sector so I can't say I know teachers personally.
I would have knowledge of telecommunications and software engineering myself but my main problem is time.
With a full time job and a young family to keep me busy I find it already difficult enough to write one post a week.

I could advertise the openschool project in my oldest son' school but he is in primary school.

This is definitely a project that's worth pursuing though. Maybe I could investigate with our department of education over here to see if they would be willing to help in finding teachers in Ireland.

Any material would be of help I think.
What about an openschool website? Maybe I could help here.
