I was just saying its hard to think of everything one could possibly do with a card for all future scenarios, not that we forgot to include something. I see folks are talking of a math coprocessor now too, that's certainly a big change in capability I wouldn't have imagined for an 8-bit processor.
We've taken the jeenode and gone way beyond that. ATMega1284 (lots more memory, more IO, 2nd serial ports), added SPI UART for more IO, added RS232 & RS485 drives (converts signal levels), added Real Time Clock with battery backup (bottom of the board), added Secure Data (SD) card. Adding RF will be straight forward, just need to pick from the myriad of transmitters, receivers, or transceivers available. Really crammed a lot of stuff into 60x80mm and 80x100mm footprints.
