Well, we had talked about it being used as either an indicator of a 
regular file transfer or an X509 delegation. Looking through the code,
there is this:

    enum TransferType { NoType, DownloadFilesType, UploadFilesType };

which has nothing to do with delegation - instead the delegation
looks to be a seperate flag, and not a "transfer type".

Well, we wouldn't want to store the actual credential, but instead some
sort of fingerprint or credential id.
