App/V (Softgrid) – application virtualisation

I’m interested in starting to use an application virtualisation technology such as App/V.

My main area of usage would be to use different versions of an application in one OS instance because I work as a Sales Engineer and my company has mutiple different versions of product that I have to support.

However App/V seems to be aimed at large scale installs rather than single user usage.

Does anybody know anything further about App/V or similiar kinds of application.
