Actually, robust standard errors for logit and some other models (glm
family) are available. The basic option is robust=TRUE, but there are
other options as well.

Dear Xavier,
I'm actually not in charge of robust standard errors; I am cc'ing my
coauthor Kosuke who implemented them.
Best,

Hello Olivia,
I've been an R user for long time and I'm starting to discover Zelig and
its abilities.
I have tried to build a logit model with robust errors and clusters for one
variable, but according to the mailing list this feature hasn't been (yet)
released (or it wasn't in october 2006):
http://lists.hmdc.harvard.edu/lists/zelig/2006_10/msg00001.html
My question is about the availability of this feature. Is it on the list of
features to include? Any idea about the possible periodicity? The questions
are just to have an idea and whether I would have to wait or program it for
myself. So in any case it pretends to be a "demand".
Since from the mailing list you seemed to be the programmer dedicated to
this functions I have sent the email directly to you.
Thank you very much for all your work.
Best regards,
