Hiding the domain fieldset based upon permissions

First off, thank you for writing this nice little module. I've found it very helpful. I'd like to talk with you all about adding a small feature to extend it's use. First, I'll describe how I've modified the module to meet my use case, then I'd like to discuss how I might submit a patch that abstracts this feature to be of more general purpose use.

My Use Case:

I've got a default site at www.mysite.org and a community site at community.mysite.org. Site visitors with the "member" role can add content that should be published to the community site. I'd like them to be able to do so from either www.mysite.org or community.mysite.org. In order to do so, I have to give them Domain Access's "publish to any assigned domain" permission.

I'm using your module to set the default domain for this content to the community site. (Actually, it's a bit more complicated than that, b/c they publish to both domains - depending upon the type of content.) In order to avoid confusion, I do /not/ want to display the domain content publishing fieldset on the node edit form. It's just not necessary - given that I'm using your module to properly assign the domain per content type.

To accomplish this, I've changed the following:

    if (!empty($default_domains)) {
      $form['domain']['domains']['#default_value'] = $default_domains;
    }

to:

    if (!empty($default_domains)) {
      $form['domain']['domains']['#default_value'] = $default_domains;
    }
    if (!user_access('set domain access')) {
      $form['domain']['#access'] = FALSE;
    }

in your hook_form_alter.

This seems to work for me, though, I don't like the dependency on esoteric permissions configuration. That said, your module is already somewhat dependent upon some less-than-straight-forward configuration settings (No offense, all Domain Access contribs seem to be...), in that "publish to any assigned domain" must be enabled for your module to work.

Thoughts? How could we abstract some of this a bit better? Rather than making the display of the domain field set on the node edit form be based upon permissions, should it be a configuration setting at /admin/build/domain/settings? Or should it be it's own permission?

Thanks in advance for your thoughts. Again, thanks a ton for your work on this tool!
