How do I access Time Capsule Remotely with iCloud?

Before, with MobileMe, I was able to backup and access my Time Capsule anywhere in the world because I had my MobileMe login stored in my Time Capsule, and my MobileMe entered into my mac.

So when I was at home it would backup through the local network and when remote it did it through the internet.

Once upgrading to iCloud this broke (even though I entered my iCloud info into the time capsule).

Apple apparently fixed this with an update:

The latest Airport Base Station Update 7.6.1 "provides support for remote access to an AirPort disk or a Time Capsule hard drive with an iCloud account."

However, I'm still unable to do it. Is there instructions some where on how to do it with the latest Airport Utility / iCloud?

Note, yes I could do it with port forwarding but that would require that I have a static IP and like most all residential users I don't have a static IP and can't afford to pay 180+ for a business account to have one. And yes, you can use something like DynDNS but that only works if you have an extra computer at home and that its always on. I only have one machine and its my laptop that I bring with me. MobileMe acted like a DynDNS on the Airport to make Back2Mac work and supposively iCloud should do the same.

Also in Airport Utility next to my iCloud login it shows a green icon (so it's connected).

Thanks in advance!
