I just discover ( and was pretty happy 
) that all 3DzzD demo was just running fine on mobile phone using SkyFire
tested with an Omnia 900i & an HTC
not really surprisng as it is a serverside based technologie (like cloud computing) but very pleasant, unfortunatly input are very bad, seems that applet only accept mouse click (or touch click for touch screen) no drag allowed and the mouse click sent take age…
but that’s a very nice tools for mobile phone that enable standard Applet to be viewed (I did not test Webstart but I guess it wont work…)
EDIT :
for people interrested in trying : here is demo (animated and wihout interaction) that you can use to test on mobile phone
