  Short answer: no (not really/not that I'm aware of).

  Long answer: AD Model Builder? WinBUGS? shortcuts like nlme applied to the proportion dying,
with appropriate scaling of the variance (weights argument)?    

   I'm afraid that a nonlinear generalized mixed model with two random effects, although fairly straightforward to define, is pretty darned difficult to solve reliably ...
