- Transparent data compression over low bandwidth lines.
Consumes a lot of CPU, therefore only recommended for
low write loads or for desperate network situations.
- Remote device: bypassing iSCSI. In essence,
/dev/mars/mydata can appear at any other cluster member
which doesn't necessarily need any local disks.
- Various smaller features and improvements.

/dev/mars/mydata can appear at any other cluster member
which doesn't necessarily need any local disks.
