I think it's unpleasant to pay run-time cost for a compile-time  
choice. Sure, sometimes the extra cost is no big deal, but sometimes  
it can be a big deal and I see no reason to choose idioms that use  
virtual functions if there are equally good or better ones that don't.

Are there really no better techniques than abstract base classes and  
virtual functions for this sort of compile-time switch? How about the  
technique used for ResourceRequest and ResourceResponse? Maybe Darin  
Fisher can explain that one.
