Microchip PIC32 family microcontrollers are Lhings supported devices. You will need some kind of network connectivity besides the raw microcontroller, like for instance the Wifi-G demo board, which features the MRF24WG0MA Wi-Fi module together with a PIC32MX family microcontroller.
Sample code for this demo board is available in Microchip Embedded source code page. Further documentation and code for Microchip products will be available soon.
Other module - microcontroller combinations should work as well with little or no modification to the sample code.
