I have just started using mysensors myself but the shared D10 pin you mention is an issue for sure.. Both the ethernet module and the RFM radio use an SPI connection to communicate. The SPI bus can be shared between multiple devices is you want (MOSI,MISO, SCK), and do so based on a separate signal "Chip Select" Each device sharing the SPI bus need to have their own dedicated CS signal to know if it is their turn to use their shared SPI bus. In you proposal however, software based SPI is used ,so both of your devices have their own data pins.. But they still need their own dedicated CS signal. Which is the signal you intend to share.. that wont work,. Also, I have been asking around if you can create a combined gateway node for both wireless (NRF/RFM based) and wired (RS485 based) communication.. From what I gather, it is not possible to combine these functions. 2 separate gateway nodes are needed.
