I have inquired further. But I'm thinking that you could use these products on your machine alone, with people in your company and then with people outside your company. Depending on th epurpose and he extent of functionality you might need anything form zero to full infrastructure support. I alos understand that, smart signature, for example, has a range of potential functionality and thus we may find that only certain functions (but not all) are enabled without infrastructure support (i use that term for all the servor level action that wave can provide). Let's face it, the details of what is being offered there are light at this point - it's not even officially launched.
