The good news is that we are currently testing our new communication protocol and it will be ready for a Beta release soon.
We have worked hard to make sure that the new SDK will be backwards compatible. There will be the addition of an initialization method, but the existing API works the same.
Our new SDK will utilize TCP/IP to communicate between the browser and a Windows service running on the client machine. The new service will be installed with DLS when upgrading to the new version. A range of ports will be available for our windows service, if the browser cannot bind to one of the ports, it will fall back to our legacy plug-in architecture. For additional security, the service will accept connections only from localhost.
Stay tuned to this blog for more information.
