Or you could ask me. :)

It's a 'proper' Rails method, but it's only exposed via Potlatch's AMF
calls, not via the XML interface used by other clients. If you wanted to
access it from a non-Flash environment you'd have to use an AMF library, in
your scripting language of choice - available at the least for Ruby, Perl,
Python and PHP - to generate the calls.

You can then call whichways_deleted(left,bottom,right,top) in
/api/0.5/amf/read to return an array of deleted ways[1] within the bbox; and
getway_old(way_id,0) to retrieve one of these deleted ways. Let me know if
you want to do this and I can explain further how the deleted way is
returned.

cheers
Richard
