EMC will do what you want and more than you asked. You can have a
zero tool length in the post processor. You can have a zero pivot
length in the post processor. EMC will calculate/compensate for the
tool length and pivot length.
EMC can also compensate for manufacturing/assembly errors for the
rotary movement of the machine axes. You can compensate XYZ to move
the machine around a perfect pivot point.

Sorry, diameter is not addressed yet. I have talked with some of
the developers about 5 axis tool diameter compensation. I believe it
should be as easy to implement as the 5 axis tool length/pivot length
compensation. OK, maybe a little more complicated but it is very
doable.

Somewhat, as I explained in the generic controller post, this is
possible. A .apt file is the extension used by APTOS/APT360 to process
and post file. With a script EMC will automatically process, post and
load the gcode into the control when you pick the .apt file to load a
program into EMC.
Other CAD/CAM systems could do this just as easily if they would
run in Linux.
You would then be able to describe the cutter in the tool table
file, have the CAD/CAM system process and post it. With the speed of
the computers this could be done in real time allowing you to do all
the things you asked about.
This would not be the perfect fix. There isn't a perfect fix, but
this would be closer.
