[Sprint Samsung Galaxy S III] zanderman112:
For Android 4.2 Try this:

Or this:

Only bug I noticed was that in order to switch from any non primary user back to the primary(as far as using a visual UI), your lock screen *has* to be in landscape mode. Easy enough I guess so have at it!

Thanks to everyone keeping the info flooding in on this subject. Hopefully KLP will have this baked in for phones as well.

Original Method for 4.1 below:

Also, I have navigation bar mod on my 7/30 build of CM10, so ignore those.

This should work on any Jellybean Android 4.1.x ROM built from AOSP, like CM10, AOKP, etc.

Please read this entire post before doing any of this!

This feature is now in AOSP fully as of Android 4.2!!

After reading about the recent discovery of multiple user code being in JB, I decided to mess with it.

Here's a video:

Manual method(fun, makes you feel like a hacker):

First, we need to enable this.

Go to Terminal Emulator and type these in:

su

pm create-user test

Hint: "test" being the name of the 2nd user. You can change that to a name, or whatever.

Now, we've created a 2nd User on your JB 4.1 device. Hold the Power/Lock button to bring up the power menu, and you should see this:

From here, you can switch to the 2nd user, which will have a fresh homescreen, and show you the tutorial. Settings are limited to this user, as seen here:

To remove this 2nd user from your phone, switch back to the primary user via the power menu, and go back to Terminal Emulator.

Type this in:

su

Hint: only if it isn't still running from before

pm remove-user 1

Hint: primary user in this case is 0, 2nd is 1, so on and so on.

Now you should only have one user, and your Power Menu should not have the ability to switch to a new user anymore.

To double check, go back to the Terminal Emulator and type this:

su

pm list-users

Should say:

Users:
UserInfo{0:Primary:3}

Easy Method:

XDA member Raghav Sood has an app that does all of the above for you.

At the moment, this isn't extremely usable, ie texts from the primary user's still show in the 2nd test account. But, with the right launcher installed, and hiding the apps from the drawer on the 2nd account, this can still be usable in its current form.

My suggestions:

1.) Label the 2nd user Guest

2.) Use Nova or Apex as the launcher for the Guest user, and hide all of the apps you want(texts, social media, email, etc) from the app drawer.

3.) Setup a security lockscreen on the primary user to prevent Guests from gaining access(each user has different lockscreen settings)
