+Abstract:
+
 MARS Light is almost a drop-in replacement for DRBD
 (that is, block-level storage replication).
 
 In contrast to plain DRBD, it works _asynchronously_ and over
-arbitrary distances.
+arbitrary distances. It uses very different technology under the
+hood, similar to transaction logging of database systems.
+
+Anytime consistency: on a secondary node, its version of the
+block device is always consistent in itself, but may be outdated
+(represent a former state from the primary side). Thanks to
+incremental replication of the transaction logfiles, usually the
+lag-behind will be only a few seconds, or parts of a second.
+
+Application and replication are completely decoupled.
+Networking problems (e.g. packet loss) have no
+impact onto your application at the primary side.
