How do I keep a double wishbone from cambering to all hell in 10" of travel?

Longer wishbones.

Or have the wishbones pointed at a great angle down when the car is just sitting, so it doesn't go past +25 or so degrees fully compressed.

Length ratio is also key. The upper CA should be around 70% of the length of the bottom one in short travel suspensions, in long travel like you mention the length of the upper CA needs to be a lot close to the length of the bottom one. In addition, the arms themselves need to be a good bit longer. Check out the front suspension on a sport ATV or a Trophy Truck to see what I mean.

In reply to 96DXCivic: Use very thin, weak wishbones and a complicated system of hydraulics and computers to forceably warp the camber curve as the suspension travels.
