[Q] has anyone extended loess() for family=binomial?

The title says it all.  I have a data set with 2 continuous predictors
and a binary dependent variable.  When I model the outcome as a function
of 1 predictor I use gam(y~lo(x1),family=binomial).  I tried to use
gam(y~lo(x1,x2),family=binomial) but ran out of RAM (I would prefer not
to reduce my sample size, but will investigate that later).

loess(y~x1*x2) works fine but the family is limited to gaussian or symmetric.
Does anyone know of an extension of loess to cope with binomial family?

I am using S-Plus for Windows V3.2

Thanks,
