Also wanted to add some info about the DKAN data portal distribution:
"Based on the Drupal-based "DKAN" variant of CKAN software, and combined with new low-cost multi-tenant Drupal hosting capabilities, we think it is the best way to rapidly cause an explosion of local government data to become published and discoverable online in a sustainable standards-compliant manner."
See these for more info:

It would be great to know if people think this is a potentially effective solution to data publishing and if it's worth collaborating to improve it for UK needs.
