Good news, we just released our Beta program for the upcoming FVP 1.5 release. You can apply for the Beta Program here:
Version 1.5 adds support for vSphere 5.5. Full support for the vSphere Web Client is available. If you are still running on vSphere 5.0 or 5.1 you will still use the vSphere Client C# client.
If you want to find out what PernixData is all about, please register for the beta and provide feedback.
