Today’s Byte is for readers who work with an office of folks … I’ll start by saying that I don’t know much about this firsthand as I don’t have an office of folks – but this looks interesting. Google is beta testing a program that would bring Gmail to every user in your domain. Since Gmail for your domain is hosted by Google, there’s no hardware or software for you to install or maintain. The Gmail accounts would include the following:

Gmail – 2 gigabytes of storage and search tools that help your users find information fast.
Google Talk – Users can call or send instant messages to their contacts for free * anytime, anywhere in the world.
Google Calendar – Users can organize their schedules and share events and calendars with others.
Control Panel – Easily manage user accounts, aliases, mailing lists, and chat settings.
