The HKIX in Hong Kong maintains a an access-list per member on its 
route server configuration, and mails out copies on a members list 
periodically so that people can check that their filter is up-to-date.

The APE in Auckland and the WIX in Wellington, New Zealand both include 
route servers which are well-used. Both route servers incorporate route 
filters for peers which are built from a citylink-operated IRR-like 
database which speaks RPSL.

So while none of these examples illustrate exchange operators requiring 
any kind of registration of routes (there are no restrictions on direct 
peering sessions across the exchanges, for example) the popularity of 
the route servers on these exchanges provides some incentive for peers 
to publish their export policies.

These might be unusual examples, of course. I have done no great survey.
