In Section 7 of Bunge-Hermida =20= we actually discuss Lack's model structure on 2-Cat(S). We did this =20 only to show that it is not suitable to get 2-stack completions, in =20 case someone would think of this idea. The (ELP) is too restrictive =20 for that. This may have led to your misunderstanding when we actually =20= agree. What we wanted (though we did not need it) was a model =20 structure similar to the Joyal-Terney but in dimension 2, and of =20 course it would be different from this one. I am sure too that it =20 exists. Best,Marta [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
