I have my solution

This is likely the best FTP server out there I have found. MIT License, and you get source code. Build it in Visual Studio
(2008 for Windows CE version is what I did
), find the executable in the directory. Was able to change default directory, authentication
(have to modify source code but it isn't too hard
). It can act as a standalone application, or you can reference the built dll as a library. I'm excited about it, just kind of ran into it in a Google search.
Thanks for the help everyone
