Web browser capability in an extension

I am writing an extension, for which I need to embed a html browser component in the html pages of the extension.

Have tried the following without any success

1. Used with a simple <iframe> - looks like DW does nto support iframe in extensions.
2. Tried to embed an applet that has web browsing capability (JDIC)
3. Adobe AIR app (using mx:HTML component) - but running an AIR app inside a browser requires the user to have AIR runtime also.
4. Adobe Flex app that inernally used iframe inside the swf file.

1,2,4 works when I open the html in browser, but not within DW.

Today i came across this link -
http://livedocs.adobe.com/en_US/Dreamweaver/9.0_Extending/help.html?content=dwr_extending_ex_09.html
- that clearly says that DW does not support applets and ActiveX in extensions.

So, how do i go about with my objective ? Are there any ways i could do this.
Plz help.
