Web hooks for platform may be relatively limited
Recent job listings suggest that iCloud may not get a MobileMe-style web interface, or at least not a complete one. The company currently has several iCloud Java Server Engineer positions open, each of which requires "5 years experience designing, implementing and supporting highly scalable applications and web services in Java." A single opening is present for an iCloud C++ Server Engineer, which involves creating and supporting "highly scalable applications and web services in C/C++ on Unix platforms," plus familiarity with Apache and HTTP servers like nginx and lighttpd.
Reports have noted that sending calendar invitations through iOS 5 currently results in a link to an iCloud webpage, which has fueled speculation that some sort of iCloud web interface is coming. At the same time, Apple has not made any mention of one and is instead pushing iCloud's hooks in Mac and iOS apps. Any web hooks might therefore be limited, just enough to interact with people who aren't using compatible apps.
