Pat,
Not sure if this will help, but I've had good luck with IVEware, free beta version at: http://www.isr.umich.edu/src/smp/ive/.
Similar to SPlus, it provides a very flexible method for MI, and there has been some work done on imputing data from complex samples (i.e., including clusters and strata as dummy variables) - see refs below.  If you're a SAS user, it may be worth a try.

I confess -- I have no idea what I'm doing.

I've got a clustered data situation, so I downloaded PAN from Joe's 
website.  I also installed Splus 6.2 for Windows, which is what Duke has.  
I unzipped the PAN files into .../splus62/library/pan/, which is where all 
of the other libraries are.

I try to load the library from the Splus GUI, and it's not in the list of 
libraries available.  I try to load it from the commandline, and get "No 
section 'pan' in the library directory."

I've never used PAN or Splus, so I have no idea where my problem is.

All help greatly appreciated.

Pat Malone
