We'd love an integration with Drupal 7 Commerce
No news on a Drupal commerce module, but Drupal integration experts Web Industries are a Xero developer partner that may be able to assist: http://webindustries.co.nz/xero-integrations – they also have a free Drupal 6 module that might be of use as a starting point.
I second this! We would kill to have a Drupal 7 Commerce integration. I mean... we would love it ;)
