I´m from Rio de janeiro, Brasil and I would be interested to inlude rio in this tour. I live now in germany and studied in HfG Schwäbisch Gmünd where I got in touch in arduino. I study in rio ate ESDI (www.esdi.uerj.br
), the first design school and very recognized(visit link for more information). I think there wouldn´t be a problem to find places for the workshops since the school belongs to the university of the state of Rio and they usually host a lot of international workshops. I´ll be happy to help with any questions and make the connection between you and the school. It is a growing field in Brasil and rio being one of the biggest cities (toguether with sao paulo) it would be very interesting and I´m sure a big audience would apply for the workshop. I´m returning to rio at the end of march to finish my studies. And besides form that, a little bit of sun at ipanema beach and a caipirinha at copacabana wouldn´t be sooo bad, right!? feel free to email me to establish a contact and exchange information.
