There's something in there about non-multihomed sites, but I'm not
familiar with it. Telebec doesn't appear to be multihomed, though.

The only other thing I can think of to avoid horrible hackery is to
convince them to colo a router for you to do eBGP to. Honestly, I
wouldn't recommend multihoming *without* BGP. One day you'll end up with
some really ugly failure mode.
