I would hazard a guess that numerically, far less than half of the ISPs
have ASNs.  We only got ours a few months ago, and out of curiousity, I
pulled out the local Yellow Pages and started doing whois's on ASNs.  I
found that only one other ISP (much larger) based out of Bucks County, PA,
appeared to have an ASN (out of approx a dozen total).

I'd guess that about a third of the ISPs are multihomed, and less than a
third of those have an ASN.
