1) While I'm always grateful for your responses, TJF, you need to 
understand that your answers almost always come across a bit ... abrupt.  I 
presume it's a language thing as I couldn't possibly convey nuance in 
German.

2) You know the libpruio architecture cold, but none of your documentation 
explains it, at all.  So, the relationship between kernel module, system 
groups, PRU, and user mode is not at all clear to newcomers who actually 
try to look at your libpruio library.

3) The reliance on FreeBASIC is an absolute non-starter for a *LOT* of 
people.  While I'm sure you find it to be a superior tool, most people 
already find the BeagleBone forbidding enough.  Adding another unfamiliar 
tool to the mix is not something most people are willing to do.

Thanks.

*Because* you shunt the request through the custom kernel module. Telling 
people that they can pinmux from userspace simply confuses people further 
who are already probably plenty confused.
