function services_session_load($sessid) {
  global $user;

  // If user's session is already loaded, just return current user's data
  if ($user->sid == $sessid) {

  // Some client/servers, like XMLRPC, do not handle cookies, so imitate it to make sess_read() function try to look for user,
  // instead of just loading anonymous user :).

  // Load session data

  // Check if it really loaded user and, for additional security, if user was logged from the same IP. If not, then revert automatically.
  if ($user->sid != $sessid) {
    services_session_unload($backup);
    return NULL;
  }

  // Prevent saving of this impersonation in case of unexpected failure.
