That sounds like a nice clean way to do it.
The only advantage I can thing of that my method may offer is that IE
will just start working if it installed. Using CoTreatClassAs I presume
you'll have to remember to hack the registry to stop Mozilla's Active X
control being used in place of IE's... unless ofcourse IE remember to
overwrite the registry keys that are used by CoTreatClassAs...
