Hello Simon and John,

I'm afraid I need to include random effects, both a random intercept and
possibly random coefficients and it doesn't look like betareg can do that.

Kevin Wright has posted wish on R-wiki for beta mixed effects model. There is no
package for this, but there was a nice article describing such a model. Well, it
is a start.
