Question : Citrix virtualization

Hello
I am running windows server 2003 ent edition.  Interested in application virtualization by using MDOP (softgrid) for testing purposes I would like the applications to be streamed even if my users go home from work.  Is citrix a good solution?  I am totally unaware of this product.
WHen I go to Citrix website I see these products:
Featured Downloads - The Latest Betas, Release Previews & More
Citrix XenApp for Windows Server 2008 - Download the Release Preview.
Citrix XenDesktop- Download the full feature Beta.
Which citrix product  I should use with server 2003 ent edition so my apps are streamed through http over the internet.

Answer : Citrix virtualization

The Industry standard virtualization applications are:

1- VMWare

www.vmware.com/

2- MS  Virtual Server

www.microsoft.com/windowsserversystem/virtualserver/

3- Virtuozzo

www.parallels.com/en/products/virtuozzo/

4- Xen

www.xensource.com/

Now as far as I know Citrix have acquired Xensource. You can check all the products and then decide which one is best for your needs.
