Re: [NANOG] Multihoming for small frys?

run into is that using the longest prefix method is the only way to
guarantee that some ISPs will not use some method such as private
peering to cause asymmetric routing back to the small fry.

....that part isn't required.   Generally any /24 will do in my 
experience except for specific cases.

Other than that, you've got it about right.
