Thanks a lot! I am surprised how fast devs are picking this up. Phasex,
Hydrogen, Rakarrack ... great work already :)

Next thing what would be good to have imo is a good software mixer with
JackSession support. Unfortunately non-mixer is not a good candidate
afaik, cause it changes port names. I don't know if Fons is still busy
with his mixer and if he has explored and made up his mind about the
actual implementation of the JackSession API already. Otherwise Jack
Audio Mixer might be a good candidate maybe: http://home.gna.org/jackmixer/

Qjackctl 0.3.8 has the possibility to use 'versioning', it makes backups
of the old folder when you overwrite it.
I wonder how much space those folders take in general and if that space
is really a problem normally.

Would be good if Torben (and/ or Rui) could comment on this.
