Application licensing...

[Steve Randall]

I am looking for the best way to implement application
licensing for a new commercial product developed
using .NET technologies. If I sell the product with a 5
user license then I need to be able to manage and enforce
this. Since the main exe will be located on a server, can
you detect the number of users 'connected' to this exe? or
is there another way? I also need to prevent the same user
running the exe more than once, even if it on a different
workstation.

Also, what is the best way to manage license keys used
when initially installing the product? Is there a set of
technologies available to handle 'product activation'
either manually or on-line via say a web service?

Any help very much appreciated.
Many thanks.
