Great post Matheus - couldn't agree more!
Just one thing to add, if you do have 'non-located' teams, capture the wall in some electronic form, send it to other teams and get them to 'copy' it onto their wall. Someone may moan about the extra work to start with but everybody should soon see the advantages.
