Microsoft to sponsor the Apache Software Foundation (ars technica)

$100,000 will pay for 1 full-time corporate developer in most markets, or maybe a bit less.

Base salaries run anywhere from $50,000-100,000 depending on location and skill set. For a
full-time employee with benefits, an office, and the usual corporate overhead, you would
multiply that by 2. Remember that in the U.S., the employer pays for medical insurance.

But the Apache foundation is a non-profit, and it presumably doesn't need to have office
buildings, a Human Resources department, or other corporate overhead. So they won't need to
multiple the base salary by 2. But still, they're unlikely to get more than one full-time
developer for $100,000.
