How about a kind of "driver-wrapper"? Maybe one could write one
fake driver - the "wrapper" - that does everything LCDd wants it to.
So when writing the real server code you would no longer have to think
about the driver(s) that is (are) really used.
For a user attaching several displays to LCDd would be like telling the
driver-wrapper which drivers to use with maybe different settings.

I know this could be done by changing the server code, too, but this
way it'd be more like splitting things up. And again it'd be like
a client/server concept, but this time LCDd is the client.

Another idea might be to make writing a driver easier than it is
already. Maybe one could create a kind of toolbox you could
use to put support for several displays into one single driver.
This way a user could decide, how to make one unit of several
displays or something like that.
Hope it helps,

Rene
