I don't know about any problems with large result sets. Of course 
there's some delay until the server has done selecting the whole table 
(or the filtered subset), but since the data is *not* transferred until 
needed there's no space or data delivery problem.
Not to speak of the *human* problem handling such large data sets.

Yes, copy/paste of rows from view data (and query tool as well) would be 
helpful and is one of the most often requested features.
