Maybe think about institutions/organizations instead of people, give each institution a weight depending on how many they might send. For instance, an institution has 10 Code4Lib followers but the reality is that they will never send more than one person. So they get a weight of "one", versus an institution that sends 10 people and their weight could be affected by the "limit" someone talked about. But, if an institution volunteered to host, their weight could be increased for 2 years. Now have C4L poll the list of slots( institutions) and if they don't have their person ready to go, close the slot and go to the next. Put the availability responsibility on the institution. ok, back to last minute shopping, I think I had too much coffee. PaulC
