Unless someone else has any better advice (I'm sure they do), you will
need two separate public ASNs. Site 1 advertises it's space out of AS1,
and site 2 advertises it's space from AS2.

I don't know that it's better advice, but another way to link the two
sites is via a tunnel (GRE or IPIP).  Use the upstream IP on each router
as the local endpoint, and then run some routing protocol over the
tunnel.

I don't speak for anybody but myself - that's enough trouble.
