Call notes

• v1 – use the WordPress core WXR exporter, put the output in a zip, rewrite URLs to reference local files (e.g. file://./wp-content/uploads), put the uploads in that same zip, tada. Don't buffer the ZIP in memory, stream-output the files straight to the client.
• v2 – ditch the core exporter, start a new one that stream-outputs WXR bytes
• v3, v4 – ?
• v5 – make that exporter re-entrant so that it can pause, resume, and produce multiple output files

Let's close this issue. The work is now done or being done in the WordPress/php-toolkit repo.
