Often, participants expect to have an IP address assigned for their use on an exchange. Usually these delegations are from a common block. Where they are not, its hard to tell an exchange from a bunch of point2point links. LINX and PAIX have IPv6 prefixes that participants can use.
or, use link-local address on IX switch as documented in draft-kato-bgp-ipv6-link-local-01.txt.
Unfortunatly, that technique does not have broad commercial implementation. In addition, there was some pushback from the IETF IDR wg on using this technique. So its still a bit "iffy", although a very elegent "haq". (we used it in LA for a while but could not get folks to adopt it.)
