There is considerably more trouble involved in instanciating an ActiveX control on the client side. You have to use the Object tag, specify a CLSID, and a codebase from which the object can be downloaded if it is not installed. The following code instanciates the MSChart control in a web page. I am taking Ed's word for it that this is possible with non-ActiveX COM controls in web pages... I have never tried it.
< OBJECT
	ID="ocxGraph"
    	CLASSID="clsid:FC25B780-75BE-11CF-8B01-444553540000"
        CODEBASE="http://activex.microsoft.com/controls/iexplorer/iechart.ocx#Version=4,70,0,1161"
    	TYPE="application/x-oleobject"
< /OBJECT >
