Noah,
You might want to look at beta regression, using the betareg package on CRAN.
There is a JSS paper here that you might find helpful:

I'm afraid that mgcv:gam can't cope with this size of data set with this
complexity of model. The model matrix alone for your first model would
require around 3 terabytes of storage. For the simplest additive model the
model matrix is `only' 1.6 Gb, but that's before you do anything with it

Since AFAIK they are related by a monotonous transformation, both
