Second of all, there’s RemoteFX. RemoteFX is an extremely exciting addition to the RDP protocol that will make RDP the natural choice for desktop virtualization on Hyper-V. As always, Quest will continue to embrace and extend the RDP protocol where needed. This will not change with RemoteFX. While we cannot disclose all the cool stuff that we have in store for the Microsoft desktop virtualization offerings, I can say that we are extremely excited about RemoteFX.

Then there’s the Dynamic Memory capability for Hyper-V which makes Hyper-V even more interesting for customers to use in their desktop virtualization projects. vWorkspace, which had a industry first integration with Hyper-V, will of course take full advantage of this. Whether or not these cool new capabilities in Hyper-V lead to people migrating from ESX to Hyper-V, Quest vWorkspace offers customers the flexibility of choice while retaining the value of existing investments (you could have ESX and Hyper-V run side by side for example).

So in summary, Quest is extremely excited with the Microsoft announcements pertaining to desktop virtualization of today because they will boost desktop virtualization in the biggest way yet and we are on course to help our customers take full advantage of that!"
