Raja -
I'm not sure if there is a limit, but it's definitely possible to have more than 2 levels. I just ran a 4-level model with xtmixed. Search the internet - there are examples online.

Raja,
If you're thinking of the GLLAMM add-on (ssc describe gllamm; also
http://www.gllamm.org/), I believe that the number of levels is
arbitrary, depending only on computational resources and the properties
of the data.
