PS: The Naval Hospital in San Diego uses EasyCHCS (predecessor to EasyEnterprise) to present CHCS data to providers via their browsers. It's been in production for a couple years now. Additionally, a small company in CA uses EsiObjects and GT.M to generate applications (non-medical). They converted the Java Gateway to a PHP gateway. Their applications are all web based.
