In absence of more suitable instrument and/or rating, couldn't a GPS or
PDA with moving map be used to descend through clouds in emergency by
zooming in and noting if and what direction the glider is turning?

Ramy,

Many GPS have a "HSI" page or at least a track derived "compass". These
would probably be easier use that watching the bread-crumb track on a
zoomed-in map. Besides, the track update rate may be much lower than the GPS
update rate in order to conserve internal track memory, though this is
usually user selectable.

Best of all, IMO, is the "panel page" on the Garmin 196 / 296 / 396.
