   c.k("\\l code");        // load analytic
   c.k("f",x,y,z);         // f[x;y;z]

   2. updates from server? polling thread.
   
   c.k("_w,:w");          // register for updates
   for(;;)u(c.k());       // u is your update function
   
   3. mix pull and push? make it all push. 
   
   c.ks("send me new page")
