i think it will be more software oriented, with server/group features worked into Apple apps more. i know putting your iTunes library on there is probably the second most used purpose besides back up. it would make sense for Apple to build in a multiuser management for a central "home" iTunes library. the same could apply for iPhoto and other things. Time Capsule will become more than just for backup, but a more user friendly general purpose external storage solution. there might be a need to start putting some more hardware in there so that the Time Capsule could do more of the legwork, but it's not entirely unfathomable that all the processing could be handled by the computers accessing it, keeping the data and maybe common configuration files on the Time Capsule drive.
