This is briefly mentioned in Neal Stephenson's Cryptonomicon. The book is well worth a read if you don't mind viewpoint shifts and slightly hokey historical spec-fic.

> slightly hokey historical spec-fic.

It's a slightly alternate universe. It's not quite our world, it just looks kind of like it from a distance. Qwghlm isn't really Skye and Lewis, it's like if you kind of wodged the Falklands and the Isle of Man into the same space.

Some of the people are kind of the same but not quite.

But from way over here, you'd be hard pushed to spot the differences, unless you looked annoyingly closely.
