Prabhu;
What evidence do you have that:
1) UUnet is/was a success,
2) if it was a success, the determining factor was its use of ATM,
rather than its first mover advantage, financial/management stucture,
industry trends, etc. For example, UUnet used ATM because that was
what the bellheads would sell them. At the time, there was no
alternative to the bellheads.
