Hi Brandt,
I wholeheartedly agree with you.
We have already developed that tool and it's called FormsViewer. You can download it from our FormsQuo website: http://formsquo.com/solution-matrix/formsviewer-download/
We expect to continue supporting the InfoPath open XML format, and to extend it with new functionality.
FormsViewer already has support for some ~20 qRules commands - those are the features that were missing from InfoPath, such as calculating difference between dates, getting input parameters, or mapping repeating data to lists, etc.
We'd be happy to show you a demo. Just email contact (AT) formsquo (DOT) com.
Refreshing and tasty,
