Your "Perspective" seems a little intentionally slanted to the negative.

You failed to mention DigitalGlobe by name and also failed to mention that DigitalGlobe received their full funding under the SLA.

I suspect is more of an issue at GeoEye than it is a "...failure of the commercial satellite imagery market"

The restrictions that you mention are also limited to countries that the US imposes trade sanctions against, so the restrictions on sales opportunities is no different than any other technology company.
