Andrew is working on making this possible.

That's possible with

  lp:puppet/trunk tag:2.6.0

Assuming that part all works fine.

We can write code to poll for new packages easily. Is hudson the right
thing for controlling the testing? Can you trigger it to run against a
package whenever we like? Or could we have a plugin so that it watches a
PPA rather than a VCS for things to do?

Without outside scripting only daily or on demand are available right
now. I think all the others make sense, but it's up to the Launchpad
team what they want to support built in, given UI and resource
constraints.
