We could find a way of incorporating OpenPGP and LDAP Server,for the ciphering and privacy bit and not be encumberd with proprietary algo's ,iv done some work with OpenPGP, it doesnt hav 2 be email encryption only&since the BTS Software is FOSS and has ip based data transfers, this shouldnt be too hard to setup, ...also the DES standard can be used...i offer 2 handle LDAP&OpenPGP servers for this endeovour.
