Sure.
You're going to create a new view under Audio. Call it DSF Files. This excellent overview will guide and explain things:
http://yabb.jriver.com/interact/index.php?topic=68960.0When you're creating the view, be sure to click the
Set rules for file display.... There, click the Import/Export button, and paste your current smartlist expression. When you OK out, you'll see the wizard filled-out to reflect what you've pasted. Alternatively, you can just use the wizard as you probably did when you built the smartlist.
Once the view is created, it should now be navigable as you want. If it is a Panes view, you'll select items in the pane. If a Categories view, you'll drill down.
To make this view available to JRemote, you'll want to customize the WebGizmo views (Tools > Options > Media Network > Advanced > Customize views for Gizmo & WebGizmo...). You can add a new section under Audio, selecting this Library Item from Standard View.
