Is there a way to get Asio working without Boost?

I know there is a version of ASIO that is not included in the Boost namespace, but even then ASIO depends on Boost, but I'm wondering if there is a way to get ASIO to work without dependencies on Boost (because I cannot include Boost into the project, for too many reasons).

No, i don't believe so. ASIO has been using boost for as long as i have heard of it. I think they're very much interconnected. But you may be interested in a tool, bcp, which lets you extract the minimal subset of boost required for the libraries that you want to use.
