There are no significant differences between CRM 4 and 2011 with respect to the service calendar.
If you need non-CRM users to be able to see data in the service calendar, then the 2 possible options I see are:
- Your current approach of getting the data into an Outlook calendar, and sharing it
- Writing a report to get the data from CRM, and render it how you want. Note that this would involve using non-Filtered views, and granting SQL permissions to the non-CRM users
