http://www.arxiv.org/abs/hep-th/0312260 is gauge covariant under A -> U*A*U^-1 + U*(dU^-1)? It is
certainly not manifestly so, but probablly there is some subtle effect which
ensures that everything works out right. But it is not transparent to me
yet.
The only idea I could come up with is to construct a boundary operator in a
similar spirit, but using slightly different techniques. This one does turn
out to be manifestly gauge covariant. Maybe it amounts to the same as the
boundary state considered by the above authors.
