I think REW just uses one channel of the soundcard, once to create a calibration file, and then the same channel becomes your measurement channel, right?

That's correct. I don't see why you couldn't use the free channel to run REW. REW allows you to choose which channel you'll be using, so just stick with the open channel.
There's an advantage to using the 'calibration file' method that REW employs. If you use a microphone and preamp setup such as the ECM8000, you can include the mic preamp in the one time soundcard calibration file setup loop, and so this helps eliminate any response anomolies in the preamp along with the correction for the soundcard.
