Drush

i am using aegir/BOA which uses drush. i dont understand how it works just yet, but i needed a question answered.
are all drupal modules able to be installed and enable using drush? i read something to the effect that wasnt the case. i get easily confused on drush issues. thanks.

Here is my current workflow:
1) download an install profile (i'm trying out openpublic) from git.
2) modify the distro.make (its called something else in OP) so you can build from your local repo.
3) drush make to a folder called build with the --working-copy flag
4) install drupal, do work, make changes to code as well as openpublic.make (for module changes and such)
Now, here comes the crappy part...
5) rebuild with drush make to take advantages of the new modules you added to the openpublic.make file
6) copy in your sites folder to the newly build folder
7) continue working

Has to be a better way, right? This is even more frustrating because you have to keep a repo inside the build as well as globally.

For reference, this is my folder structure

master-profile-repo builds/ openpublic-build1/ (drupal core) sites/... profiles/openpublic (another copy of the repo) openpublic-build2/ (repeat) drush
