Hey Patrick!
I'm pretty good friends with the guys at QuBit. In fact, they hired me to help them get PD working on the Nebulae! I only wrote some basic tests for it, but people are definitely using it for PD.
pd-vanilla is what it ships with, but with some work it may be possible to include compiled PD objects from pd-extended.
There are definitely custom Csound patches available online. Not sure about any PD ones. They do supply templates for PD patches that work. I was the one who wrote it (though they might have tweaked it a bit since then.)
It's a great sounding module that I highly recommend. Let me know if you have any more questions about it on or off list.
