Now I didn't actually try this (yet), but one thing that reduces the
practical value of these models is missing values. Is there any
provision to handle these? Someone mentioned code to handle
multivariate normals with missings earlier today, how do the two
packages get along? 

I did some special cases of this for a project a couple of years back
where I did polynomial curve fits to repeated measurements of bone
metabolism data. In those data, an overall rate of 10% missing data
would result in losing half the data set for complete-case analyses.
