==== Hardware ====
  * upgrade to Cortex-M processor to talk up to 3Mbps
  * Galvanic isolation between the servo side and the computer side


==== Firmware ====
  * Add bulk_read emulation support. Make it possible to disable emulation as it would be necessary if there are any MX servos on the line.
  * Pass every character through instead of retaining them. The servos should happily ignore any Dynamixel command that they do not understand...


==== Software ====
  * make a low level, performance-oriented C Dynamixel library that would support every functionality (including sync_read and bulk_read...) and multiple interfaces. Make it easy to make binding for (cf Dynamixel SDK).
  * Make bindings for that library
