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...
