Isn't this a inherent limitation of the technology, not a Amazon one?
Trying to have multiple Operating Systems working on one actual disk
is ripe for disaster (the volumes are low level block devices). How
will locking and such work? never heard of connecting one physical
disk to multiple machines.

Of course you can access one physical disk from multiple machines via
NFS etc, and see no reason why this cant work on EC2 - then the actual
access to the physical drive is marshaled by one OS.

Maybe Amazon will offer NAS - which could be a EBS with a mini
(non-configurable) instance that uses NFS (or similar) to expose the
'drive' to multiple instances.
