No, that looks like the way to go for me.

Absolutely, it is on my schedule since months.
I have a concept for ALT on paper, PAR as well.
There are a number of things which I need to
implement them efficiently, like notification
and broadcast channels, tiny messenger objects
which can link one tasklet to multiple channels,
Will come next time, when I finished the IronPort port.
