Question on this.  Is there any interest in clustered block media?

Eg., what if five systems all had access to the same chunk of (virtual)  
disk via iSCSI.  Is there a way that one of those five could create an
EXT3 filesystem on that raw block-space such that all of the five 
clustered systems would see an EXT3 partition (and be able to use it 
concurrently)?

Oh... and a side-comment.  CIFS tries, and gets fairly close, to copy 
lovsl FS semantics.  The problem is that those semantics are DOS, OS/2, 
and NTFS semantics.  The protocol has support for all of these, and there 
are some folks who have tried to add Unix semantics as well.
