That's a helpful resource, thanks.
Does qjackctl start applications as well?
I don't see how Nama could to know to load

a particular project, say "three_blind_mice".

Perhaps qjackctl could execute a shell command like:
screen -X -S audio screen -t Nama - three blind mice -p- -- nama three_blind_mice
or
rxvt -e nama three_blind_mice
I'm especially interested non-GUI tools, since Nama caters

to users who don't run X.  Unfortunately the git repository

for pyjacksm appears to be offline. :-(
