nlme only fits models with normally distributed residual error (and
normally distributed random effects). lmer (in the lme4) package fits
models with exponential-family individual effects (i.e. GLMMs), but
that doesn't include beta
I don't know offhand of any package in R proper that will fit this model,
although you could try Jim Lindsey's 'repeated' package
<http://popgen.unimaas.nl/~jlindsey/rcode.html> or one of the HGLM
packages. There are R interfaces to WinBUGS and AD Model Builder
(possibly among others).
