Will policy support help Google Chrome make enterprise gains?
One thing which might help is the addition of policy support to Chrome. With administrators able to control things like access to Wrench > Options, extension installs, and content settings, they might just be a little more willing to deploy Chrome on their corporate machines -- where manageability is a primary concern. There's still the tech support hurdle to overcome: many large businesses outsource their IT help desks and Chrome support skills could be in short supply. It's still a very young browser, after all.
Google also recently introduced an .MSI package for Chrome, and that too could help further adoption. The .MSI allows for machine-wide installs into the Program Files directory rather than into your Application Data folder and should make deployment a painless procedure (at least the install portion).
