The "betareg" package provides a function betamix() for finite mixture 
models of beta regressions (which may be beta distributions if no 
regressors are included). Maybe that is useful for you? It is described in 
the vignette("betareg-ext", package = "betareg").

Not in betamix(). Parameters are estimated freely.
