What you are talking about isn't really Anycast from the perspective of the
rest of the world since what you're saying sounds like you'll just be single-
homed behind HE.
Regardless of whether you peer with HE in multiple locations or just one, the
AS path is still going to be the same and will enter into 6939 at whatever the
BGP-closest point is - the Anycast aspect essentially exists only between you
Providing HE are configuring a discriminator across their iBGP routers to take
the shortest path at entry points you're not directly peered to, the whole
thing should Just Work, sudden topology changes notwithstanding.
