Nested HtmlPlaceHolder fails to display content

[James]

So we have set up a Silverlight site.  As part of this site we display third party content (which we do not control) inside of an HtmlPlaceHolder control.  Some of this third party content makes use of Silverlight and Telerik as well, and in doing so make use of the HtmlPlaceholder control.  The problem that we are running into is that the nested third-party silverlight apps completely fail to display any of their content in their HtmlPlaceHolder control. So the hierarchy of content consists of the following:

HTML Page (us)
Silverlight App (us)
HtmlPlaceHolder control (us)
HTML page (3rd party)
Silverlight App (3rd party)
HtmlPlaceHolder control (3rd Party)  - FAILS to display any content

Any ideas?  Is there a fix for this?  If so, could you provide a working sample of this scenario?

Thanks,
James
