My theory (please keep me honest) is that the Monitor RGB output is progressive as most VGA resolutions out there. I can't even see a reason why it would be interlaced in the first place as the Atari Monitors are not TVs, and it was simpler to implement a progressive frame versus interlaced.
This is very encouraging!
The converters I've bought before have been Scart-RGB and the converters have been trying to deal with the supposedly interlaced signal in crappy ways to get a progressive HDMI stream.
As for interlace; the Atari screens will show an interlaced signal like any other crt screen from the time being. Just hook up a Falcon or Amiga and have a look, it will be fine. Atari even shipped DB19->DIN13 adapters for the Falcon so you could use the Atari colour (and mono) screens with it.

I second StEeLz, there's no reason why it shouldn't work -- there's no TV crap anywhere, just pure R/G/B signals converted to the HDMI standard. But after hearing Evil's experience I wasn't so confident anymore, glad to hear my doubts cleared.
I think you're missing the point; ST RGB out is 15.5 kHz horizontal frequency, "normal" VGA is 31 kHz or above. For the same reason that the most modern tft screens won't display 15.5 kHz, many converters won't do it either.
Sometimes the hardware supports the low frequency, but the software puts up a box above the perfectly good Atari image displaying something like "Unsupported signal". It's annoying when shitty software ruin hardware that seems decent. And sometimes the hardware will really not do 15.5 kHz even if it's trying and show a scrambled screen.
But this cheap little thing seems encouraging, I'll order one.
Things to look for
a) Input lag, if you want to play games
b) Interlaced support
c) Switch between interlace/progressive
d) Border cropping (will we see the entire screen?)
e) Eventual post filters (scaling etc)
