Well, maybe not everything, but the document entitled PowerShell Remoting Protocol Specification contains 179 pages of details of what Powershell Remoting does! It’s not for the faint of heart, to say the least as it very detailed – just the sort of hard core techie details that the true PowerShell addict will lap up!
This document is one of the many Communications Protocols that Microsoft has been publishing. You can download the specific PDF for the PowerShell Remoting Specification, or download a zip file with all the PDF files for all the published specifications. The latter might be overkill even for the most hardened network geek.
