Cool, that's actually pretty nice!

Wanna share your code? The original program was just a simple proof of
concept, but we can integrate code there. live data was on my wishlist
as well. :)

BTW, what happened to your QT visualizer?

That's similar to what is included in the Linux patch.

Putting all together into one "standard output" is a great idea!

Actually I'm not much of a webdeveloper and have no idea of HTML5 etc, or h=
ow to
design such a "java-script friendly HTTP server app" - implementing yet ano=
ther
HTTP server is probably not a good idea? But any proposals is welcome
- maybe something which can run on OpenWRT as well so these guys can enjoy
the spectral features on their WRT and TP-Link routers. :)

Cheers,
