Ideal Hobby Machine

A post on MaxNC caused me to redirect people here and consider the
goal of an ideal home machine setup.

In my opinion, the ideal would be a 5 axis unit one could optionally
hang over a 4'x8' router table with more beef for chipping inertia
yet still light enough (or modular enough) to make it easy to
transport by hand. Perhaps instead of synchronous motors it would
use ordinary DC motors with better position sensors as I've read that
is possible. Add safeguards like strain guages to eliminate over
feeding, skating, and breaking bits while automatically detecting
maximum efficiency rates.

Important improvements would be in software so it could better enable
major runtime tweaks and perform manual operation for the quick
unprogrammed job. The software should be written in an easy to read
and modify language like GBasic or Perl (?) and be "open source." The
poor GCodes produced by say BobCad which errantly traverse to a new
position while the Z axis is still moving would be eliminated while
adding easier repositioning of the origin point and easy repeating of
the code to adjust for best depth of cut for the stock.

Other improvements or ideas for the perfect machine? Perhaps keeping
costs at minimum by designing a kit where the initial setup could
supply jigs for the hobbiest to machine the kit parts starting with a
hand drill?
