I think this discussion is going in the right direction. My suggestion
to marry those two contradicting views would be like this:

- in normal circumstances two heads act like two separate dwm instances
  (the way I guess most people are doing now), you can jump between them
  the usual way (ie. sh -c 'DISPLAY=:0.1 swarp 512 384');

- both heads have their own freely settable sets of tags (like two
  separate dwm instances);

- add another property to a client (called head, for example),
  signifying which head a client should appear on (mutually exclusive,
  so that we don't try do display a client on both heads;

- allow changing the "head" property for a client with a keyboard-bound
  function while preserving other attributes of the client (tagset,
  float/non-float);

Do you think this makes sense?
