Thank you everybody for your inputs and good suggestions!

I think I'll do a step by step with pictures and link to it on the product page. That way one can get a good idea how to go about before buying. And also I'd make sure there would be proper links (and working) for the encoders.

There is a version 2.0 (something) BETA of the RTEncoder being tested for cross platform use. Hopefully it will be done and released soon.

Again, thanks everybody!
