Thanks all for your replies!
And is there any way to remotely observe and control more than one cgminer at once? I know possibilities of CGWatcher. Though it has some issues (e.g. no possibility to control more than one instance at once as different gpu threads may be set in separate cgminer instancies only or quit-and-BSOD issue of some R9 290 gpu's).
For my purposes it would be enough to somehow watch running cgminers' information gathered in one piece and to control them through TV or it's analog if needed.
Guy, how do you do all this stuff? Maybe somebody has found perfect solution to all that?
