Other companies have a more comprehensive cross-platform solution already. E.g., http://www.zenprise.com/solutions/mobile-application-managem... -- not only does this let you deploy apps selectively to iOS and Android devices belonging to specific users/groups in your enterprise, it also tracks all data/files these apps touch on the phone and makes sure that data is killed whenever the apps are removed or the phone is lost/stolen. Also does the same for downloaded email local-store or downloaded email attachments.

If an enterprise is Android-only, the Google solution is OK. If you're really doing a corporate deployment, something like Zenprise is a better way to go.
