Microsoft published an interesting 90-minutes virtual lab on its TechNet facility about SoftGrid:
In this lab, you will walk-through performing a Virtual File System (VFS) installation of an application as well as a sequencing of a web-based plug-in. Before working on this lab, you should be familiar with the basic concepts of the SoftGrid environment.
Setting up a lab for SoftGrid may be time consuming and resources demanding, so this online facility is highly recommended for ones that never had a chance to try the product.
