This is pretty much the conclusion we've come to as well. scott -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.1 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE5ECsBpXyM95IyRhURAmONAJ44NVwzw5DPDAOjz/Dzy//ND7ZKXwCeJZsP rxGOeCOsYKMOh1Jw89McZCI= =9PRJ -----END PGP SIGNATURE----- _______________________________________________ Freenet-dev mailing list Freenet-dev at lists.sourceforge.net http://lists.sourceforge.net/mailman/listinfo/freenet-dev
