You can use fs to server any file:

Router.route('/static/:filename', function (){
  var fs = Npm.require('fs'),
      path = '/tmp/' + this.params.filename; // make sure to validate input here

  // read the file
  var chunk = fs.createReadStream(path);

  // prepare HTTP headers
  var headers = {}, // add Content-type, Content-Lenght etc. if you need
      statusCode = 200; // everything is OK, also could be 404, 500 etc.

  // out content of the file to the output stream
  this.response.writeHead(statusCode, headers);
  chunk.pipe(this.response);
});
