Analog should be ok since dropped packages aren't a big deal, but  
with digital it matters a lot, the difference between getting a  
button press and not.

There are now some nice sensors that output analog values so they are  
really easy to use with Arduino and Firmata:

3-axis accellerometer:

ultrasonic rangefinder:

Also, for the old pulseIn() PING sensors, it should be possible to  
make a Firmata compatible firmware using the Firmata library.  It's  
alpha, but the Firmata firmware already uses the library to send  
input data.

Looking at things from a more basic level, you can come up with a  
more direct solution... It may sound small in theory, but it in  
practice, it can change entire economies.     - Amy Smith
