what I had in mind was something even less stressfull but maybe hard
to make. and it is split the HD44780 driver even further so that
the actual 'bus' connection is fully separated from the HD44780 core.

which would make things like supporting different connections even simpler

from memory there are some major HD44780 connections:

-parport
-i2c
-serial-to-paralell (obsolete by now)
-gpio (from Martin Hejl's, although it uses a parport emulation)
-some other that I can't recall
