I am currently using both CAN ports on the mbed controller. And have wanted to add another two CAN buses, to create a Interceptor style device. You can see my current CANProject device here CANProject in action. I found some free code which I have modified for the LPC1768 which and adapted it to use the mbeds SPI library. Its still a work in progress mcp2515, and would love some feedback or help.
I will post some schematics shortly, its pretty simple. Basically uses a MCP2515 SPI to CAN IC and a MCP2551 CAN transceiver.
