What are the differences in available Orion functionality with a Nephele subscription vs a standard OEM Orion license?

For the most part, the full range of Orion functionality and platform support are available to Nephele customers. Just the following Orion capabilities are currently not available with Nephele:

• Support for .NET applications.
• Fuzzy machine fingerprinting libraries for flexible multiple-parameter node locking.
• Support for redistributing Orion license server installations to your enterprise end customers. Note however that Nephele enables you to host floating licenses over the Internet.
• Support for outbound back office integration from the Orion server to external systems. Note that inbound backoffice integration is supported via REST based Web Services APIs.
• Availability of the Orion license proxy server for use as a forward proxy server for client-side high network availability and access from secure networks. Note however that the Orion client libraries provide direct support for industry-standard HTTP proxy servers.

The functionality restrictions are primarily due to technical factors, and will largely be removed over time.
