ECF has just released version 3.5.4. See here for download.
Through our github repo, we now have new OSGi remote services provider based upon Restlet. This allows Restlet to be used as the underlying implementation for OSGi remote services.
The small size and simple implementation of the Restlet-based provider (as well as all the providers) is made possible by ECF's provider architecture. This architecture also allows any transport (rest-based or not) to be easily used to implement any OSGi remote service.
It's probably unnecessary to say, but the use of OSGi services (and remote services), brings many systemic advantages...including built-in support for dynamism, security, version management, modularity, among other things.
