Update: Apple has sent two different email to iOS and Mac developers -- the latter asking makers of software for OS X to submit iCloud-compatible apps today. Developers will be able to create apps that keep documents up to date across multiple machines thanks to iCloud, which automatically stores and pushes content to all your devices.
As a Mac Developer Program member you can now download the GM seeds of OS X Lion 10.7.2 and Xcode 4.2 and submit your iCloud enabled apps to the Mac App Store. With iCloud Storage APIs, your apps can store documents and key value data in iCloud. The documents are automatically kept up to date on all devices.
iCloud will be available on the next Lion software update, version 10.7.2, which has been seeded as GM today to developers for final testing.
