You might want to look at sketch and sodipodi. Maybe you'll find
what
you are looking for. But both have IIRC no explicit tablet support.
I do not like the work flow of either of the programs you mentioned,
they do not currently support any type of artistic stroke that can be
controlled via wacom.
The approach I intend to use is a hybrid of raster and vector
techniques. Essentually What I want to do is have autotrace convert a
bitmap image stroke by stroke rather than all at once (problem areas at
the moment are where strokes overlap).... I then need to be able to
display move and delete objects and purhaps change their stacking order.

I am not sure. To extend Gimp with a general vector infrastructure
(in
fact I am working on something like this, but progress is slow since
I
am very busy with other stuff right now) a lot of work has to be
done.
Starting a new project would be silly in my eyes. There are some
interesting vector programs out there and the gimp is not the most
obvious possible target.
Um I am not seeing anything to my liking currently.... gyve I can't get
a compile of... Sodipodi's workflow is too contorted... And I find the
Koffice component and sketch don't work the way I do at all. If you can
tell me of any other project I would be greatful.

Currently this is not possible. It would be cool though...
This is planned though? soonish?

You can attach arbitrary data to regular layers. This is waht
dynamic
text does. You can modify text rendered by dynamic text with all
tools,
however, if you change the text it will get re-rendered and all
changes
are lost. Of course someone could do the same with the gfig plugin.
It is planned to make this mechanism more generic. For example to
have
adjustment layers or - as you intended - to have real vector layers.
I was hoping to do something that works and try something more elegant
and the point where gegl is folded into the main code base... 2.O right.

libart is used to do vector -> raster conversions and is thus
exactly
the opposite thing to autotrace :-)
It is mainly used to convert bezier-curves to selections.
Thanks for your input
