ARM
Broaden the target market to include ARM based systems. With ARM based servers coming round the corner, ARM v8 64-bit and ARM devices scattered in every corner of technology, it would make sense to distribute a version of RHEL capable of running on the ARM chipset.
Other distros have much better ports/integration.
Red Hat (through Fedora) should take the lead in this area and bind the distribution Gold releases to the ARM platform as well as i386/x86_64.
Yes - there are things that ARM can't do as well as Intel/AMD CPU's, but there are also things that it does better.
Although I'm thinking about creating large farms of cheap, low-energy app servers here, it's not beyond the realm of possibility to see this as a good virtualisation platform either. Especially with HP's Project Moonshot on the go.
