Yes.. The same filter function right now catches the BMC calls on the
Dell 1850 and the SuperIO serial port configuration on one of the two
Winbond SuperIO chips of the Kontron 986LCD-M.... This works for 5
boards, but maybe not even that when people start using SerialICE more
intensely.

Yes, absolutely. What about this... (see attachment)

There's also a lua class library and some more or less complex
implementations mentioned at
http://lua-users.org/wiki/ObjectOrientedProgramming.
