I wonder how big the audience is for this. As far as I know, you are my only user of MuraxArduino. (I hope to get more with SaxonArduino).
I wonder how many people who read your blog post, will have the hardware and the skills to build and run MuraxArduino.
The SaxonArduino FPGA configuration is currently part of the SaxonSoc repository, which might get it more users. I also hope to support a lot more boards. The minimal system I currently have running works on the Blackice II and the TinyFPGA BX.
One way to make these things a little easier to use is to run them in a VirtualBox VM. I am currently running MuraxArduino and SaxonArduino that way. That makes them available to Windows (and Mac) users, and it would be possible to set up VMs with everything pre-installed.
