Sure - that's the whole idea about DiSEqC ;-)

Well, I wouldn't rule out such a possibility, but for the moment I suggest
you manually enter the necessary lines into your 'diseqc.conf' file and it should
work.

Currently there are several other things that have to be completed for the
final 1.2.0. I guess "real" motor support will be something for the 1.3.x
developer branch...
