Syncing 2012 Essentials and Standard AD

I am about to sell a server solution to a customer where they will have an on-site 2012 Essentials server for their small SMB, and a couple of hosted desktops for remote workers. The hosted desktops will be running on a 2012 standard DC. Are there any issues linking an Essentials Primary DC, to a Standard secondary DC?

The Secondary DC is hosted by our cloud hosting partner, so we cannot choose the software there, but the customers own on-site DC really doesn't need to be anything more than the essentials version of 2012, saving them money. They currently only have 15 users, and aren't planning to grow within the next 5 years.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Essentials (2011, 2012, 2012 R2) supports having additional replica DCs within the same domain. Child domains or other trusts, however, cannot be used. So as long as your domain tree is flat, this works fine. Essentials will also need to continue to hold all FSMO roles.

They MAY have to purchase Server 2012 CALs now though - Essentials doesn't require them, but if you add another server, CALs are typically required.  You should ensure they consult a licensing expert to confirm their status (keep in mind advice offered online is a best efforts attempt and laws and locations can affect the accuracy of any advice given).
