UAG 2010 SP4 and RDS 2012 publishing remote apps

Hi all,

I have a question about UAG and RDS 2012 app publishing.

As read from UAG SP3 (not different from SP4) release notes it is not possible to publish remote apps on RDS 2012 by UAG acting as a RDS GW. 

But could it be possible to publish the RDS Gateway server by means of a Web Application? I mean, the RDS Gateway will only provide a web interface to the user, and RDS specific protocol is used between the RDS Gateway and broker / RDS Session host server.. 

We already have a RDS 2012 environment and do not plan on degrading to Server 2008 :)

Thanks.
