.. my turn to impress :-)

I've peverted your code in the worst possible way and made it work on
a live data stream.

:-)

I have FreeBSD's ath driver now enabling and triggering spectral scan
(if configured this way) on each channel reset/change, so I can gather
spectral samples during a scan.

I'll tinker with this a little more, but I'm honestly at the point
where I think you and I should just agree on a javascript-friendly
encoding scheme and write a HTTP server app that just reads in a live
or recorded data stream, then feeds it serialised out HTTP. That way
people can just write HTML5 renderers (which leverage all the
GL/accelaration they want) and we can benefit from having a shared
visualisation tool. :-)

What do you think?
