Agreed, and what'd be nice would be a language by language generalization of this sort of mechanism, ideally to move the binding to a DOM implementation out of the code and into the environment. This can be done for COM as you've demonstrated, it can also be done for Java, and probably for any language/platform which supports dynamic loading. The crucial thing is that all COM DOMs use the same mechanism (including some agreement on Win registry keys), all the Java DOMs do likewise (including the specification of a Java system property), and ditto for all the other implementation languages which can support such a mechanism. If that's going to happen at all it'll have to happen under the auspices of the DOM WG. Note tho', that this involves stepping outside of IDL to give us an entry point to bootstrap into the main DOM interfaces.
