OK, let's try a similar but different scenario.  Customer has ISP A, 
adds ISP B ("you").  Customer intends to disconnect from ISP A. 
Assuming the customer told you, do you require the customer to start 
their connection with you as a private AS, do you require the customer 
to re-AS-number later, or do you assume the customer will re-multihome, 
etc.?

And what if the customer doesn't tell you that they're intending to 
leave ISP A?  Do you police this, and if so how regularly?

(And yes, Patrick, IKYNAI.  We'll pretend for the moment.)
