We are loading locale files using Nodes' fs.readFileSync here: http://nodejs.org/api/fs.html#fs_fs_readfilesync_filename_encoding
Do you plan on supporting file open as well as require? It would be great if it reloaded when file opens are used.
No. But if you pass the file contents to the vm module and specify the full path as [filename] argument, node-dev will watch that file.
