The 'beta' status of lavaan implies that things (eg function arguments) 
may change from one version to another, until most planned features are 
implemented. However, the computations/results themselves are pretty 
stable. Many SEM reseachers do use lavaan today for simulation studies, 
and some have been published already. I can provide you with some 
references off-list if you are interested.
