I've considered doing exactly this (using Node.js) based on the same paradigm as the Unreal Engine. Epic devised a very effective way to code for both a client and server at once within the same class(es), where server->client, client->server, and other types of replication are as easy and intuitive as anything else. I think it would be perfect for real-time web applications where multiple users interact with each other at the same time. I'd advise anyone interested in these ideas to check out how the Unreal Engine does it.
