Ericom AccessNow for Quest vWorkspace vs vWorkspace client

Hi,

We have seen that Ericom AccessNow product could let us open RDSH or VDI services to any operating system and greatly without any installation on end user devices.

We've seen that this product exists too for Quest vWorkspace : http://www.ericom.com/AccessNowforQuestvWorkspace.asp.

Did you have any technical comparison between AccessNow and vWorkspace client for several operating systems ?

We are interested on any experience (test or production) of Quest customers.

Thanks

Fabrice
