Hosted BlackBerry Enterprise Server for Google Apps is offered by ExchangeMyMail. This means you can get ~90% of the BES experience with Google Apps.
Goggle seems to spread their net over the world. We all know Google, since it's beginning, has been growing by leaps and bounds. Google is slowly penetrating every part of our lives. It's everywhere. And I guess, almost 80% of what we do on the Internet, is being recorded by the Google Servers. Is it scary? It's like a huge directory of information on each and every person on the planet, dead or alive. Why only people, they have records of each and every kind of organism that ever existed. Well, in a nutshell, all our data is distributed, and exists in the cloud.
If you want to be part of it, try the new BES for Google Apps.

"With Google Apps Connector for BlackBerry Enterprise Server, you can integrate the Google Apps messaging suite with BlackBerry devices, letting business professionals use built-in BlackBerry applications for push-based wireless access to their Google Apps email, calendar, and contacts. Business users can continue to use their BlackBerry devices without interrupting productivity."
Pricing (seems quite expensive to me): Account setup fee: $50.00, each user: $9.99/mo. I'm not sure if the price includes the email fee for Google Apps Premier but at least we could hope for it. Nevertheless, you will have to have a BES capable plan from your carrier, since it will still require BES support.
