Robust SEs in GLMMs

It is not too hard to set up a cluster bootstrap (i.e. clusters are
sampled) for clustered data, although I'm not certain what happens with
spatial data. It then takes a bit of time to run.

delete-d jackknife and other subsampling approaches are good for more 
complex correlation structures.
