What you could do either by editing the webserver configuration or by adding an .htaccess file is make it so your html pages can contain php code. Then you can just use the External Use code for the Post Islands right in your .html pages.
Right now that's probably the only way, as to even use the RSS portion of it would require it to be parsed out before it would display.
I do need to get in an option to use the content islands via javascript, but they've changed quite a bit and haven't figured out a way to do that completely yet.
