Limited duration demo client?

Hi all,

I have friends that are *considering* getting Guild Wars and I can't help but think that if ArenaNet allowed existing account holders to pass out something akin to the friend's pass that would give them access for say 24hours, or 1 weekend, i'm sure my friends would then be convinced and they would rush out and buy the game...

does anyone know if ArenaNet intend on doing something like this? a limited duration demo client perhaps?

That would be nice.

EDIT: Maybe limit to pre-searing.

yeah, that would work fine... hope they do it at some stage.
