Looking at it, I'd have some questions and/or suggestions:

Do we have time to do the switch? Or, do you think that by implementing this, we
could save some time when implementing the RRTypes we don't yet have and leave
the current Rdata implementations as they are?

So, will this allow that several different RRTypes will be represented by a
single concrete class?

I was thinking, if they have no member variables, all their methods could be
static and we could use them in a template-like manner instead of using virtual
functions. These could be inlined and we could gain some more performance and
possibly more type safety. Then we could create new Rdata classes by just
defining the list as template parameter somehow. Would it make sense?

Like (using the type list approach):

  class SRV : public RDataImplementation<P<IntField, P<IntField, P<Int16Field, P<NameField, EndList> > > > > { };

With regards
