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 ...
