Hi there.
Since there has been a "Linux-Software-Competition" for more than one year (without any result), I simply wrote a control-software (aquaero-info).
It is a text-mode-program, and lets you change or view any setting of aquaero. There's also a status-page, telling you current temperatures, fan-speeds, and more (in the end I had so much fun in writing it, so that I added colors to the output).
For now, it's an independent program - but in the future there's also a daemon planned.
The source-code (being under LGPL) can be downloaded at:
http://breakbe.at/development/aquaero/
All important information is included in the source-distribution, too.
cheers chris
