It's just what you thought, foil tape for shielding.  There is a whole 
variety of types available many of them copper.  The type with the quilted
pattern usually has conductive glue.  I use it mostly during the bread-board
phase for shielding between high gain sections when necessary.  It also comes
in handy during FFC testing to help identify problem 'holes' emitting 
excessive RF.  I have used it to provide some ground plane on vector board
however the heat of soldering tends to do a number on the glue.  It's usually
pretty expensive stuff as well.
