  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 ...
