If you want to have your home computer download any time, even when you are not there... this is how you do it.
As previously noted you can not set up hellanzb to find the nzb on your idisk without your idisk being where everything else goes too. Of course that is impossible with the size of the files etc.
Why do you want your idisk picking up the NZBs?
Well if your leave your hellanzb computer running at home, and you are at work or on the laptop on one of your other computers, you can save an NZB to your idisk that hellanzb will automatically start processing at your home. So when you get home there it is, downloaded and expanded for you exactly as you like.
The problem is, using OS X's built in Alias creating (putting an alias of your Idisk location on your drive running hellanzb) will not work, it doesn't reference it properly for the unix situation.
You will need
"MakeSymlink" which once installed will allow you to properly set up a symlink or alias on your hard drive that references your idisk. This is confirmed working with hellanzb.
Awesome. Now I can download anywhere anytime, as long as I leave my computer running!
