Is the new finder encryption option compatible with lion?

[Jaben3421]

Hi Everyone,
I was wondering. I recently had a flash drive stolen, and want to encrypt it so if it happens again, they won't be able to access my data again. I then noticed that Finder nows allows you to encrypt a GPT drive in the Mountain Lion DP preview. I was wondering if you encrypt it using this new feature in Mountain Lion, is it compatible with Lion, or Snow Leopard, since I have other computers running those operating systems and need to know if I can still swap data or will finder not recognize it? Has anyone tried this? Thanks...

Lion introduced this encryption however the ability to encrypt disks is only accessible from Disk Utility. The drive should be compatible with Lion.

Encrypted (non-sparse) disk images (AES-128) should be compatible with SL, Lion and ML. You can create them with Disk Utility.
