I don't know how possible it is in Scoop, but the "Read More" link could be modified so that it automatically loads the thread as dynamic threaded... Should be a feature request for ET 2.0. Having a "low bandwidth" option so that some threads are automatically loaded as dynamic.

And warning users to beware of loading the thread is simply a matter of asking InWales and LEP to insert the appropriate text above the fold...
