    A C# Web User Control is an ASP.Net UI element that renders HTML, this is
    not what I am doing.

    A C# User Control on the other hand is a Window Forms UI element, which can
    be hosted similar to an ActiveX control, inside IE using the <object
    classid="http:blah.dll#namespace.controlclass"> tag.

    Oh and nothing is impossible... a Web User Control could use DirectX coupled
    with a javascript refresh to render a 3d scene, but lets no go there unless
    several gallons of booze are involved :)
