For ActiveSync, it is my understanding that for a *server* (like  
Horde's groupware stack) the license fees are not per user, but per  
server. Client software I believe is per user. Additionally, it is  
also my understanding that it is the provider of the software that is  
responsible for selling the licenses (again, this would be Horde).

We have looked into the possibility of providing licenses for  
ActiveSync, but there needs to be a large enough demand for the  
licenses in order for us to recoup the initial, very substantial,  
up-front royalty fees that would be due to Microsoft.

Zarafa's Z-Push, as well as any other EAS implementation is also  
subject to the same restrictions as Horde when used in the US. It is  
my guess that since they are not physically located in the US and they  
don't allow the source to be hosted on US servers, they have decided  
to ignore the patent issue.
