Hello; the agents don't currently support this, though this is something that we've considered for a long time -- some of our key customers have requested this as well. However, we've developed some interesting technical alternatives that make the pull-based agents largely moot (at least according to the folks who requested it originally); for example Romp and universal packages allow the client to self-install, or at least have an in-house BuildMaster or Otter instance that can manage installations based on packages.
