+. Implement the vsnames options in the mysql, svn and sys handlers, the same
+ way as it already works in the duplicity and rdiff handlers. Then edit the
+ corresponding helpers to make them use the lib/vserver functions to support
+ this option.

+. Factorize the rdiff.helper's connection-related functions into a lib, so
+ that they can be used by dup.helper too. (NB: don't forget that the dup
+ handler has a sshoptions configuration setting, that is often used to
+ specify an alternative SSH key, or a specific IP to bind to.)
