No, but you can do what I tend to do in "push" cases...  Either have the 
request able to time out (think poll()) or do something where if nothing 
interesting came back, wait.

e.g.

while(!done) {
 s=getstatus();
 switch(s) {
  case one: dosomething; break;
  case two: dosomething; break;
  case three: dosomething; break;
  default: sleep(5);
 }
}

Basically if something interesting came from the status request, deal with it 
and immediately ask for more.  If nothing intersting came up, sleep for a 
bit.

Works through NAT, doesn't break the client/server model and scales relatively 
well, especially if you have that sleep do 5s+some random number of hundred 
milliseconds.
