I have to chime in here I think it is wrong for software company to offer a product feature and claim they do not support it. If you don't support it then don't use it in your software. You guys are a php outfit that is fine then do php if your going to incorporate flash into your product then you should support it.
As a developer if I told my boss I wanted to use a third party piece of software to achieve functionality but that we couldn't support it we simply would not be able to use it.
Don't offer what you can't support. Nice feature but if you can't support it then don't incorporate it.
