Apple's WWDC 2011 opening keynote is just hours away - don't forget to join us for the SlashGear liveblog! - but that hasn't stopped the leaks, rumors and speculation. iCloud is already on the agenda, and according to a Cult of Mac source it's not just a cloud music service but a way to put your entire Time Machine backups onto a new, intelligent Time Capsule. What's currently a basic NAS will, they suggest, get an Apple A4 or A5 processor upgrade as the Airport Express is tipped to, and be able to host users' Home folders and make them available to any Mac OS X or iOS device.
That would mean iCloud users could access their desktop files from their smartphone while out and about, even if the desktop is turned off at the time, with automatic synchronization of any updated documents when the desktop is powered on again. "Your computer gets backed up to Time Capsule anyways," the source pointed out. "Now it’ll serve up your content when you want it, where you want it, right there on your iOS device."
OS X Lion - also expected to be detailed later today - already has such support built in, with Versions for handling multiple copies of files and Resume for getting you back up to speed with the documents you were working on previously. It's not the first time we've heard of such file-sync functionality; rumors back in April suggested Apple's software engineers were busily working on beta versions of iOS 5 and OS X Lion to test the system internally.
