No problem running BGP on a 9.6Kbps line if all you want is a default route from your ISP (to detect if the link is OK) and advertise a couple of routes to the ISPs (so they can detect if you are up). Just keep in mind that there is what is technically feasible and there is what your ISP is willing to sell you. The former usually only influences the latter negatively.
In regards to transiting traffic... No--this is a matter of filtering what you are advertising, rather than a matter of how many routers you have connected. Use an as-path access-list to permit only prefixes with an as path of ^$, and this should take care of your transiting worries. You can also use a prefix list to limit what you advertise to prefixes you are originating.
BGP will run fine over a 64k link, as long as your traffic doesn't overcome it.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
