Sounds good ;)

Yes, its a hidden option in the configuration (meaning you should backup
your config, manually adapt it and restore the adapted config)
The minimum being 10seconds (everything less then 60seconds is not supported
btw) and no upper maximum ;)

Good question, i've been wondering about this myself. It would be nice if
people could sent there own experience. Offcourse it depends on the hardware
itself and the re-authenticate interval. Without the 1minute re-authenticate
interval quite alot i think.

Well, since threading is not that easy, its currently not implemented yet
and I still would need to program code which splits up the tasks into

Not really, everything depends on your personal setup.
