Don't want to get ahead of myself considering the eMBee ONE isn't even working yet, but thought I'd keep a log of ideas for future plans:

Hardware

• Adafruit RFM69 radio transceivers so that eMBee ONEs can communicate with each other

Software

• BEEP command (so you can easily do stuff with the buzzer on pin 5)
• CHR$ support
• User defined graphics? Change character sets to make text-based games more interesting
