We were discussing this over here, and the big question we came up with is: "Does this mean that simply raw devices a la old school Red Hat (/dev/raw/raw1) are desupported, or that all character/non-buffered IO devices are desupported (a la /dev/rdsk/c0t0d0s2 or /dev/sda2 with O_DIRECT)?" If the former, it's a non-issue for most environments, if it's the latter, it opens up a host of questions around what will be supported. Effectively, it requires that people have a clustered filesystem to use, or somehow Oracle jobbies up ASM such that you can put OCR and voting internally and making ASM a dependency for CRS to run.
