I had an LPC fan ask if he could get the source and continue the work so I published it in a Git repo. He was going to port it to LPC11xx but AFAIK he's done nothing with it, maybe he looked at the code and thought it was crap
I myself have been too deep into a Due-like hardware design to do much more with LARD (Lpc ARDuino). When this design is finished I hope to start a range of small network nodes for the Due board, they will use the LPC11C24 (with CAN controller/transceivers) and at that point I will resurrect LARD.
At present you can (almost) cut and paste a simple Arduino program and have it run, it's C though so things like Serial.xx() have to be changed to Serial_xx() etc.
I would like to do more work on it but priorities are priorities.
EDIT: Using the LPC11C24 allows a network node to be made with a single chip plus a regulator and still have full CAN support, very small, great for your railway layouts
