Fair Compensation For Non-Compete Clauses?

LL writes "This article notes how non-compete job contracts allows indirect control of one's actions, even after leaving the direct employment of a company. Apart from the business ethics of using them as anti-competitive measures (a separate topic by itself), the question is what should be a fair compensation for removing yourself from the technology environment where skills suffer alarming bit-rot? Other sectors (e.g. banking) have 'gardening leave' where they basically pay you to remove yourself from the 'inner fraternity' before joining a competitor, but what should be a fair compensation for an enforced pause in your career? 6 months @ 150% base pay? 200% @ 3 months? Or are there standard clauses that IT workers have widely accepted as the norm?"
