Hi Gareth,
yes you can relate my example to dropping the artefacts into htdocs on apache or inetpub/wwwroot on IIS.
It still uses the ICF but it simply serves this content directly from the file system. It supports caching (CACHECTRL=+28800) and directory browsing (BROWSEDIR=2). There is no need for the browser to authenticate either.
Once you move to an ABAP stack that has the SAPUI5 add-in installed you will find the libraries are located somewhere like http://mysapserver/sap/public/bc/ui5_ui5/1/resources/sap-ui-core.js
Cheers
