Apple considering two WWDC per year for iOS and OS X?

We're hoisting the rumor flag on this one, but Hardmac are reporting that Apple may be considering making WWDC a twice-yearly event.  According to one of their "most reliable sources" the Cupertino company is looking at the possibility of two developer conferences, one dealing with the freshly-named iOS (for iPad, iPhone and iPod touch) and the other focusing on Mac OS X.

The move would allow for more targeted keynotes, workshops and other sessions, suited to developers who may only code for one half of Apple's product line.  It would also fit in well with speculation – including from our own Michael Gartenberg – that Apple are looking to leverage iOS as a platform not just for smartphones and tablets, but an overall ecosystem of connected devices and screens.
