// In most cases the data object is already signed here (e.g., if it is generated by a local
// application, or was received from another node). The only reason to check if we should
// sign the data object here, is if a data object was generated internally by Haggle -- in
// which case the data object might not have a signature (e.g., the data object is a node
// description).

// FIXME: data objects should really be signed in the SecurityHelper thread since
// it is a potentially CPU intensive operation. But it is currently not possible
// to ensure that the signing operation has finished in the helper thread before
// the data object is actually sent on the wire by the protocol manager.
// To handle this situation, we probably need to add a new public event for
// security related operations, after which the security manager generates the
// real send event.
