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.
