I filed bug #684617 for this (see [1]).

That sounds interesting. I remember Ubuntu Studio as a similar approach 
and the website libregraphicsworld.org and am interested in reading your 
blog. When I was more often on the Linux side I liked to use 
Digikam+GIMP and played around a bit with Darktable.

I the past I saw 'No Dynamics' or 'Pressure Opacity' as defaults.

There's no bigger intention behind it. I checked various Dynamics 
settings, but overlooked 'Pencil Generic'. So everybody can use 'Pencil 
Generic' instead of building a new Dynamics preset.

Obviously no, as we already have the 'Pencil Generic' preset.

Yes, that's great. The 'Device status' tab gives you a smart way to 
switch the settings for each physical pointer device.

Indeed, because it allows a more natural workflow as you described then.
I think another prerequisite is 'multi-pen' support by the tablet. If 
the tablet doesn't distinguish multiple pens then no graphics program 
will be able to handle them separately. I already saw some tablets with 
multi-touch support (like the Wacom Intuos series), maybe they can do 
it. But please try and report back ;-)

Kind regards,
