According to Rixstep, Developers planning on marketing software for 10.7 will submit their products to the App Store as iPhone and now iPad developers have already done. 10.7 will have kernel support for ('insistence on') binaries signed with Apple's root certificate. No software will be able to run on Mac OS X 10.7 without being approved and signed by Apple, Inc.
Apple will supposedly begin signing up independent software vendors (ISVs) for the 10.7 developer program by early autumn 2010. Rixstep expects that there will be efforts to jailbreak OS X 10.7 just as there have been with the iPhone.
