Currently it is not yet able to manage sessions at all. What it can is
everything else (from the list i've mentioned) except the port
virtualization stuff that I plan to implement in ladish. It will be able
to relaunch apps, and connect their ports. It will (and already is) able
to do some other related stuff.

I guess, this depends on the distro you use. I recently suitched to
gentoo and I made ebuilds for it. In past I've contributed jack2,
laditools and lash-0.6.x deb packages to ubuntustudio team.

It will handle them nicely. It will display notification that app crash
was detected and will ask you whether to relaunch it, unless you want it
never or always to do so (user configurable option). When relaunched
jack ports associated with the application will get reconnected and its
internal state will get restored (given that app has internal state and
supports restoration of internal state). Internal state and connections
will be restored from the last saved snapshot.

LADI is still not able to do session management. ladish can do jack
multiconfig however. laditools allow you quite a lot of things regarding
JACK monitoring and management. Currently LADI is [mostly] tested by me
only. If you are affraid of being early adopter, you should probably not
do test it until contributions of other early adopters make it more
suitable for you.
