On the actual embedded device this is handled by a kernel module.  We
can spit commands into it as fast as we can and the kernel module can
keep up.  This is typical unix device file behavior.

Any suggestions or advice would be splendid.  Thanks!

Assuming you are on unix, have you considered FIFO's, os.mkfifo()?
