Thanks a lot. This would indeed solve the problem. I'll try mkdist today ;-)

Is the NEWS file parsed before of after mkdist has been executed?

Would you be willing to share the code for the infrastructure, perhaps 
on GitHub?

Each GitHub commit triggers a build (branches are supported as the branch info is passed in the WebHook) which can be either "classic" R CMD build or a custom shell script (hence you can do anything you want). The result is a tar ball (which includes the generated files) and that tar ball gets published in the R package repository. R CMD  check is run as well on the tar ball and the results are published.
