Allow the click once client installer to be installed for All Users

Although the click once has improved the install the fact you have to install it per user is a pain. Please can we have the option to install for All Users instead of per user. Also, instead of having one installer per program, could there be a splash screen where you tick the components required and the installer runs...clearly this is no longer a one click however it really isn't a one click installer as it stands in any case.
