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 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.

Currently this is not possible. It would be cool though.

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.

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.

Hope this helps,
