I've never used the Twitter API or Meerkat, but it seems that the 'choke' could be bypassed by scraping followers/following info from the publicly accessible profile pages of users.<p>Eg, sign on to Meerkat via Twitter, get username, scrape user's Twitter profile page for connected users, check if these connected users are on Meerkat, ask the user which of them he/she wants to connect with on Meerkat, then add on Meerkat.<p>Am I missing something? (I'm sure I am.)
