This is great. So much better than distributing APKs over email or something of that nature. The ability to push secure updates to internal apps through Google's network is gamechanging.
Less relevant (unless you're on the free Google Apps plan, or want to do private apps outside a domain) now that this is available, but using Dropbox/GDrive for private app distribution is far less painful than email.
(I imagine it wouldn't be too difficult to build a pseudo-Market over the GDrive APIs for such uses. Might look into that at some point.)
There is a product called Knappsack that I have been using to help with this problem... www.knappsack.com . Gives you a private app store, cross-platform, open source or SaaS.
