[O] Still Wishing for Snooze

[Andrew M. Nuxoll]

A while ago I posted for help in adding an ability to "snooze" a to-do item:

At the time, the only solution available was to create a manual copy of 
the item.  This approach creates as many problems as it solves for me.  
I've gotten so frustrated with this that I'm really to knuckle under and 
fix it myself.

I'd like to modify the org-mode code to support the following:

1.  Add a date tag to an entry that indicates that it is "inactive" 
until a certain date.  I'm picturing something like this:

***** TODO [#B] Verify login to the virtual machines
      SCHEDULED: <2013-01-11 Tue +1w> DELAY: <2013-01-24 Thu>

2.  Add a command similar to org-deadline that I can use to attach a 
delay date to a to-do item

3.  When I display my agenda, items that are delayed are not displayed.

My e-lisp is pretty rusty so *any* advice or help is great.  Could 
someone help point me to the right files and functions I'll need to 
modify to accomplish this?

Thanks,
Andrew
