Chris adds:

She states in an interview that "the hero has to go on alone".  To me
that sounds like he (Albus) is really dead.

Another interesting thought, we know that Mundungus was banned from
the Hog's Head, and that the barman (Aberforth) has a good memory. 
However, we see the two of them in Hogsmead, possibly doing business.
Why is Aberforth dealing with 'Dung?

And Pam chimes in with a theory of her own:

I am forming a theory as I am finishing up reading GOF to my 8 year old (and dreading going on to 5).  Dumbledore mentions his brother and says he's not sure he can read.  But he turns up in the picture of the original Order of the Phoenix, and he remains in the Wizarding world in a low level job.  Why would Dumbledore "not know" if his brother can read?  I was thinking:  suppose Albus and Aberforth were both great wizards in the Order.  And suppose something happened to Aberforth during the first war that left him with reduced mental capacities (ala the Longbottoms).  He may act bizarrely (maybe a little two bizarrely), but he can hold a job and may possess some information or be the keeper of some important artifact.  That would explain Dumbledore not being sure about his brother's abilities, and it would explain his association with Mundungus.  
...and what if there are more Dumbledores out there in the world? Any thoughts?
