Death and portraits

As Snape's memories attest in DH, Dumbledore is still able to
comprehend and influence events that occurred after his death.  In
particular, I am thinking of his telling Snape to deliver the sword to
the Forest of Dean.  It seems odd to call someone dead when he can
still act in this way, and I don't recall any other portraits having
quite that sort of ability (or if they did, they never seem to have
used it).  Are there others that anyone recalls, and can we truly call
Dumbledore dead when he still has such a hand in the story?
