Flushable diapers?

So, who here has tried these new "gDiapers"? They came from Austrailia, they are like cloth (a liner with a cover) but the liner is flushable instead of having to wash it (so a cross betwen disposable & cloth) but they say they're better due to not ending up in a landfill.

I'm looking for opinions, as I haven't used them, but wonder if they are worth getting for busy times (I usually use cloth). Here's the link for those who are interested: www.gdiapers.com
