From what I understand of Veteran's Affairs, the technology has been built, and it does sell. The only problem is that the government's being fleeced for all its got by the vendors in question.

VA's got no end of computer systems, where its staff hand-enter information in one system, print out its report, only to scan it, fax it across the country, where someone else will hand-enter it into... A different system.

Engineers, consultants, and Serious Business Contracts were involved in the construction of this abomination - and while they were all in compliance of the standards that the government expects from its vendors, none of them delivered a good product.
