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.
Yours
Paul Christ
