I had a look through the source code and I would seriously suggest nobody use this application, there doesn't seem to be anything malicious but it is very poorly designed. It is parsing the Antminer web interface rather than hooking into the cgminer API. Loading the HTML interface on the Antminer takes up excess processing power and should be avoided at all costs especially on S1 which runs a MIPS based control board. Using this application could very well cause instability and reduce your hash rate.
Feel free to design a better one! Last I checked the cgminer API isn't open to any IP except "localhost", which means the Ant's IP. That means you have to know how to get in there to change it.
This is designed to be pnp, just like the Ants.
I ran this against my S1s for weeks before I initially released it, with no problems, and no decrease in hash rate.
I did warn against running the refresh rate too low.
I think that "poorly designed" is a bit harsh, honestly.
