It's possilble to publish applications via Group Policy or other application from the class of desktop management tools. With Group Policy there's more need to publish applications like a scripts where's some need to preconfigure them for concrete environment they are oriented to be deployed on. But when we switched to Desktop Authority, a desktop management tool from Scriptlogic, it turned out that most the things I did previosly via scripts which sometimes very slow and buggy I can do right from the Desktop Authority's console. Its something of what I did via group policy management but when with GMPC I need to create complex sets of GPOs where each represented specific tune for a specific case, here I can do that right from one place. For example I am able to publish and run applications that require high-level user privileges on boxes where user rights are limited to default users. So if application requires installing servies to run on a client, I don't have problems with launching it on user desktop, because I can run applications with administrative privileges without using runas command.
