You can if it has USB access to the drive.
@Helen: We had stated previously that for Apple time capsule, "You can if it has USB access to the drive," but we believe that the time capsule USB port in the back is only for connecting printers and possibly additional drives to the time capsule. We don't believe it is for using the time capsule drive over USB.
@E. Siemens: Thanks for clarifying it also for us. Yes, we do intend to have NAS support. Specifically for Apple time capsule, we have not looked into it, and it would depend on what network protocols we can utilize to reach it.
Okay, can I hook it up directly to my Airport Extreme and have it act as the conduit to funnel the pics to my Time Capsule?

We assume you want to back up to Time Capsule over NAS. We are not users of Time Capsule, and we have performed no test at all, but if your Time Capsule drive is accessible as a network mountable drive, the short answer is yes when we implement NAS support.
