The following are some screenshots of what internally we have been calling "ASL Web", or the "Stand Alone GUI" (SAG?). I like ASL Web better myself, and this is only the first of two related interface projects we've been working on. In terms of layout, its very similar to the existing Plesk modules, the core differences are that the entire interface has been redone using DHTML, and it uses its own internal authentication system.

This means it uses a separate authentication mechanism, with its own users and passwords independent of the system, or any control panel you would configure to use it with. This also facilitates the use of an ASL interface with non-Plesk systems (Ensim, Webmin, Cpanel, Nothing, etc).  

Internally it runs its own separate instance of apache, on a different port from the regular apache. Just like on Plesk up to 8.6, except in our case we're using the apache shipped by the vendor.  We intend on getting this into [asl-2.0-testing] before the end of the month, and it will be available for all platforms (CentOS/RHEL and Fedora).
