Commercial company offers money for open source bugfixes

This could be really neat. From Surfin’ Safari:

Karelia Software is working on an exciting new app that uses WebKit: Sandvox. This web authoring tool is shaping up to be rather spiffy and elegant. But they need your help. There’s a couple of bugs in WebKit which are impeding their progress and that they’d really like fixed soon. So they are generously offering bounties for fixes.

Except look at how much money they are offering. $250! They are asking expert developers to put their overhead, expertise, and time into solving another company’s problems. I can’t imagine that these bugs that Apple has not been able to fix yet will take any less than 10 hours for someone to fix. At a modest $100 an hour, they should be offering $1000 minumum per commited bug.
