Which is why I suggested trying it on ONE service and watching it
closely.  What I have done is selected a "best candidate" for a test.  I
am not implying that "this is guaranteed to work".

0.1% of users is a HUGE number if you have 1,000,000 subscribers.  Are
you prepared to field 1,000 helpdesk calls or lose 1,000 customers?  Now
imagine 100,000,000 subscribers.  Are you ready for 10,000 support calls
or the loss of 10,000 paying customers? 

It isn't something you just throw out there on a whim and tell people to
like it or lump it if there are potentially a lot of people involved.
