SMS is aimed at ease of use and precision. Although I am surprised to ear about SMS's and Pduino's speed problems.
I made an installation with an SSC-32 servo controller controlling 24 servos connected to PD. The SSC-32 is based on the SAME chip as the Arduino and uses a communication protocol VERY similar to SMS and I never experienced any problems.
Maybe you are not keeping your messages simple enough?
Or maybe the big difference was that I was using a hardware serial port and not a USB>Serial chip/converter.

So, SMS is signicantly slower because it uses ASCII conversion ?
Interesting. Even at high baud rates ?
