title: Proxy Facebook chat to bypass firewall
body: <p>We built a flash application using XIFF XMPP to integrate with Facebook chat.</p>
  
  <p>Problem is we found out a lot of firewalls out there do not allow Jabber (ports 5222, 5221).</p>
  
  <p>So I was wondering if anyone tried to set-up a BOSH implementation (or something else) as a proxy to Facebook's chat for clients who are blocked by a firewall.</p>
  
  <p>Thanks
