My company is lame, and I can only really install software via Homebrew without a lengthy approval and packaging process.
Have you thought about adding Juggler to Homebrew?
Hmm, that's interesting - I certainly had 'homebrew' on my to-do-list, but quite low down, but you make a good argument for making it a higher priority..
We're phasing homebrew out in my organization, so I wouldn't focus on tailoring to it. .dmg files are fine and good. but homebrew sort of fell apart with its automatic updates that break things. If I am looking to install a single package, I'm not expecting homebrew to install 200 of them. Yet that's what's happening now, and is the reason I'm advocating phasing homebrew out. My two cents.
