ActiveX and RDL

Is there any element that is supported by RDL that will allow an ActiveX control to be embedded into a Reporting Services report?

The ActiveX control doesn't need to be scripted, but only listed as an object tag with some parameter tags within it. I'm looking for something like this:

<ActiveXControl Name="Control1">
<ClassID>...</ClassID>
<Parameters>
<Parameter>
<Name>Param1</Name>
<Value>Value1</Value>
</Parameter>
</Parameters>
</ActiveXControl>

I understand that an ActiveX control doesn't really make sense in any context outside of HTML, but the ability to do this would be very valuable to a lot of consumers I think. I am already aware of CustomReportItem, but I've been told the functionality of that element is limited to outputting an image.

Does such a construct exist?

Thanks.

For a while, we actually had this in RDL but we cut it because you could not do data binding for the control. We were also concerned about security and the cross-platform issues. We might bring it back in the future but no workaround for SQL 2005.
