That site is a little outdated because Chrome now natively supports multiple user profiles. Each profile gets its own icon and there's a user profile switcher next to your tabs. It's by far the best solution to the multiple accounts issue.
The google voice integration is by far the worst. I have to log into google voice, which then calls my gmail, which then calls whoever I want to.
Go to the Chrome settings page, and under the "Users" heading, choose "Add New User." Then you can pick an icon, that appears up in the browser's title bar. That icon helps you remember what user you're browsing under.
It might ask you if you want to setup sync after creating a user, but you can just close that window and it won't ask you again.
Click the icon in the top right corner of the title bar, and you can change what user you're browsing as at the moment.
My company uses Google Apps for Business, but that basically means web services, because no actual software works. GChat, Chrome, etc all fail to recognize the account.
Yep just tried again: Invalid user name and password. Exact same entry as when logging into email except Chrome fails where gmail.com works. It simply will not accept the name/password of my Google Apps account on any Google software.
What a bummer, was hoping this was a fix for having multiple accounts.
Didn't realize there was anything more than possible.
To do so, have them visit:

...and Ctrl-F "Google Chrome Sync"
