Is there any NTSC encoding on it? Can I wire up a composite or Svideo jack for TVs that don't have YUV?

Short answer is no - GreenAntz transcodes colour space from RGB to YPbPr ("component"), which is different to the colour space for svideo or composite.
GreenAntz doesn't convert video into NTSC or PAL, as this is unnecessary. It creates a composite sync from separate horizontal and vertical sync, but it doesn't do anything to change the video mode timings. That means you get the same flexibility for video modes as an RGB TV or monitor, but with a component TV.
Component TVs are comparable to RGB in quality, which makes component TVs more attractive to retrogamers. Some composite or svideo input TVs can be often be modded to take RGB inputs, but in many cases it is easier to mod TVs for component input.

Nice job, boys! I'd go for one, but i built one of the prototypes which works just fine :)

Thanks! We've come a long way since those giddy days, I have a box full of old prototypes now :lol
Some improvements we've made since then include:
- voltage regulation
- improved colour & luma balance
- decent composite sync generation from H&V (rather than "cleaned smushy" sync)
- better integration of the "sync tip" with the luma (Y)
- onboard VGA, USB & RCA jacks
- mounting feet
- cool art!
We will also produce an updated SCART version soon (once the audio jacks come in from Lala Land).
