Dear kerberos people, please find appended our sales paper about BelWue which we think is probably one of the most advanced science networks of the world - comprising a CRAY2 in Stuttgart, a VP400 in Karlsruhe and a VP100 in Kaiserslautern, 200 km full-speed 10 Mbit/sec Ethernet trunks and about 1000 Workstations. We would be eventually interested in your famous kerberos system. Please could you send us some information concerning technical and legal questions.
