Can a Coldfusion 9 license still be purchased?

You would need to purchase CF11 volume license, and request for downgrade to CF9.

Please contact cfinstal@adobe.com for more information.

Note: As CF9 is end of life, we will not be able to help you with any issues,  bugs, security hotfixes, vulnerabilities etc..

Thanks,

Rahul

Not that I am aware of, the product version has reached End Of Life: Adobe products and technical support periods covered under the new Lifecycle Policy  so in addition to not being for sale, it is also no longer supported by Adobe.

You might try contacting sales directly: http://www.adobe.com/products/coldfusion-family/buying-guide.displayTab5.html
