I have worked for 3 ISP's in the past several years.  Of the three 2 peer at
the MAE (actually the connection for one of them is still sitting in
MaBell's in box).  This is a prohibitively small sample to be useful though.
At most the number of ISP's dualhoming must be <= the number of assigned
ASN#'s.  As for leaving their NSP, I am not sure that many are doing that.
Its hard as hell to do without killling your customers.
