I am currently working on a Framework that provides a nice set of
classes that will enable
the user to inherit such things as list, string, tree etc. Persistence
is supported by the very base
parent object in so much as it will enable classes to be packed into a
flat buffer which can be saved to
disk, or squirted down a serial port, tcp/ip socket connection what
ever...

I would like to release a very low functionality version so that people
can add,change whatever they
think is needed.  At the very basic level the design is a cross between
some of the MFC classes, and
the Booch framework design.

Well if we put both of our efforts towards it we may save some time and
effort and not end up writing
the same stuff as each other.
