On the off chance that someone else finds this useful, If I am at the 
web interface and click "HostGroup Overview" and then click the 
hostgroup that is in () ie. (flux-lab) for me, I am then given the 
option of "Scheduling downtime for all hosts in this hostgroup" which is 
what I wanted.

I'm not sure what's up with the duration being set to a default of 7200 
mins or 2hrs but I'm hoping if I select "Fixed" and use Start / End 
dates that I'll be ok. If not, my boss is going to kill me for taking 
down our mail server with lots and lots of email.

Why is this option not available for the main "Downtime" option on the 
web interface? Is there any kind of bug tracker of feature tracker I can 
check out? It seems like I should be able to schedule this from the 
"Downtime" menu shouldn't I?

Is it a common practice to have a hostgroup like 'allhosts' and have 
every hostgroup I define listed there? The physical plant here at UT 
likes to turn off power to our building often times and this situation 
comes up quite often.

I know, I know, where's the patch right? I wish I could help...
