1. Won't work if you want them to access concurrently (unless there is some
new funky cluster feature I'm not aware of)
2. Probably best option for compatibility across the board without 'extra'
drivers needed, maybe an issue if you have a Windows guest later on.
Performance considerations needed if there is high IO expected.
3. Yeah, samba, hmm, unless you are doing Windows, I'd stay away.
