There was an interesting meeting yesterday around 1pm (evening for most participants) on IRC's #Wikimedia-chapters. It wasn't a private meeting as anybody could attend, but it wasn't advertised either. It's not directly related to USA-organizational efforts, but it's chapters-related and it might influence the USA situation in a tangential way. Delphine and I attended for the chapcom, although Delphine did most of the talking.
Some volunteers have been looking into organizing speakers of the Catalan language. Catalan is spoken in parts of Spain, France, and Italy, and is the official language of Andorra. Organizers, who come from all of these countries are proposing to create the first transnational Wikimedia Chapter.
This raises a couple problems, notably due to the overlapping with existing chapters in France and Italy, and another proposed chapter in Spain. The organizers were, however, very well prepared for the meeting and had a number of specific plans and ideas in mind that would indeed require some sort of legal framework like that required of our chapters. Questions and ideas were exchanged on both sides of the table, and we're taking a week for both sides to think things over. We're having another meeting next Wednesday at 1pm EST (5 pm UTC) to continue the discussion and see where we could be moving from here.
