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.

Well in the Seattle area there are at least 3 providers who have switched
NSPs over the years. Of course, as far as I know, all of them had portable
address space at the time.
