Removed old accel_server and replaced with new python accel module and edited the setup script to install it.
I tried to split it up as much as possible already, I added the same section markers that were in the led_driver. By "limit the amount of verbose code" do you mean you want me to change the lines:

if ret < 0:
    PY_ERROR

 Because if I put that in a C function I would still need some of the PyErr_SetString lines and it would just be a bunch of:

if ret < 0:
    return -1;

lines in the C function instead which wouldn't make the code any shorter.
