Would it be possible to provide the option for using the variance-covariance matrix rather than indicator data as the input? Christian mentioned recently that LVPLS provides an algorithm for doing so.

This option would also solve the problem of not currently being able to analysis weighted data sets, since the variances/covariances can be computed on a weighted basis. I have used this trick with AMOS to enable weighted models to be run (although what it does to the interpretation of significance of results, I don't know).
