help with foss in schools case studies

hit a bit of a road block with our roll out of suse for education.

We need to have a strong and valid argument from some where else to show 
that other are actually using it.

I would like close to complete studies, with as many "big names" so it 
can't be just dismissed.

Also does any one know what can cause broken packet to cause a network 
to collapse?

Apparently it's us, but all I have got is suse 11 box just installed 
with patches?

Anything would be helpfully, like the stuff going on in Spain schools etc
