I had a look at it and found it rather complicated and confusing. Is
there any documentation available?

Am I right that this is not really a plugin system but more a program
laucher that starts small programs if certain keys have been found?

Will every device driver need a seperate process to run? A seperate
daemon for every device?

What do I need to add a trackpad driver for example?
