This is an interesting question - what context are you using the term meeting space.

See Robyn Munford et al for writing on disability.

HI. Thanks for the answer.

The context is a meeting space (virtual or not) to enable individuals with ID meet each others and extend their social network.  

Sport events which you can find people with ID competing, like special olympics and some events organized by International Paralympic Committee (IPC).

Yes in NZ we have opportuniities for people to meet through the People's First organisation.

The virtual space is not same the real space... and the people with intellectual disabilities could have more different needs: for people with alzheimer's, for example, is not indicated the white walls; for people with ASD it requires special attention to sensory input (light, noise, etc.) who in some of them could cause ansia, stress e addirittura dolore. Is very complex this teme. 

Some interesting contributions at the link...but only in italian language sorry :-)

Check out Ed Hall's work on learning disability theatre and decline of traditional day services. I also have written on 'self-build support networks' in wake of declining day services.

Here's something in Ireland based on engaging in the arts
