Using ebMS as transport protocol for RegRep

The following came up in discussions with a cross-border e-health initiative in Europe: they use the IHE specifications which are based on ebXML RegRep 3.0 and the WSDL/SOAP transport binding. Earlier versions of RegRep included an ebMS 2.0 SMTP transport binding, which was used in the past by IHE. The 3.0 and 4.0 versions of RegRep provide Web Services and REST bindings, but no ebMS binding. The 2.0 version of ebMS has been used in various national healthcare initiatives and at some point there was interest in ebMS 3.0 in the HL7 transport group. In Europe ebMS 3.0 is being adopted for various cross-border data exchanges and the question is if healthcare should converge with this. Such convergence could be done by providing an ebMS 3.0 transport binding for RegRep, which the higher-level IHE specifications are layered on, though the main question would be if there would be any market for such a transport binding. Is anyone aware of any recent interest in using ebMS (in particular ebMS 3.0) with RegRep in healthcare in other geographies, or in domains other than healthcare?
