having worked as a support engineer (until a recent layoff) for eiStream (link), I know that they have software capable of all aspects of what you seek.
the WMS division of the company produces software that focuses on digitization of processed forms, OCR, workflow management and the like. the trickiest part of this process, however, may be for their off the shelf product to incorporate all your specific aspects (or requirements) into one application/process. i would also be interested to see how they handle your request as it nearly fits an as of yet (and perpetually unreleased) new product. regardless, it shouldn't be impossible to accomplish what you seek with what they have available.
as with many companies, they have an professional services group willing to come on site to customize the application to your project, performance tune the hardware and software, and help you learn the product some...
the core OCR software can be sampled with a 60 day trial download (link) of the Imaging Pro (Windows users only...) software. the obvious down side to this company (other than my layoff), is that the required server hardware and licensing costs can become cumbersome. it really all depends on the scale/scope of the project and how many documents you seek to simultaneously process... the PSO group can scope that for you before hand though if you want. oh yeah, and its nowhere near open source...
