David has already replied about the complexity of such references.

Squeak is a virtual computer that runs on a variety of hosts. For Squeak 
processes, the host is just another remote computer. The best way to access 
these resources will be through URIs with protocol handlers in the VM for each 
type of resource (e.g. program:/pdflatex, plugin:/SerialPlugin or font:/Sans). 
URIs can even handle device ports (e.g. serial:/1 or video:/1). Such URIs can 
safely be persisted in objects across snapshot ops.

I suspect most people use Squeak on a single platform, so the itch is not 
serious enough ;-) for a URI.
