Ghosts! - kind of long

We've seen how when JKR introduces small details or characters, they 
often become major factors in future books.  I've been thinking a lot 
lately about the Ghosts in the series.

There are a number of ghosts with minor roles: Nearly Headless Nick, 
the Bloody Baron, Myrtle, Professor Binns, and Sir "properly 
decapitated Podmore" to name a few.  I imagine that the ghosts will 
play a major role in the new war, but I'm not quite sure what.

Maybe the ghosts will take sides in fighting the war?  I can see the 
Bloody Baron supporting LV, while Nick, Myrtle, and others support 
the Order.

And there was the whole scene in OOP with Harry asking Nick why some 
people become ghosts when they die.  I'm sure we'll learn more about 
this in Book 6.

And I think this has been mentioned somewhere already, but Podmore is 
probably related to Sturgis Podmore.  JKR wouldn't re-use such an 
unusual name if there wasn't something more behind it.

Any thoughts/theories on what will happen with Ghosts in books 6 and 
7?
