Could you please send me a pic or further description of what you mean? It sounds interesting and I'm trying to wrap my head around it but I guess I've simply never seen it.

Like that, except finished and/or polished.
It sounds interesting though somewhat against the simplicity of the current desk. As I detail in another comment, it's not solid wood so it would be pretty easy to create the recessed outlet and a path through the tabletop...
