So basically I'm implementing dojo into a new chat system I'm working on.

We are trying to support as many people as possible, and I'm trying to figure out if we are approaching this the right way. So if anyone can answer any of my questions that would be great.

1. Can Dojo work with the firefox plugin: NoScript
2. Are the complications with referencing the javascript file on a different domain as the site is servered on (ie: googleapis)
3. Is Dojo as reliable as Iframes, or do developers really still have to deal with that. If so, can dojo also fall back onto iframes?

Are the dijit themes included with the default dijit installation (tundra,soria,nihilo) 100% complete and cross-browser compatible? I noticed that soria and nihilo in particular use a lot of pngs, and am wondering how ie6 would handle these two themes. I am running Ubuntu Linux, and am therefore unable to test the themes myself. I need to use a theme which is completely cross-platform, as many Windows users visit my website. Thanks in advance!
