merge replication licensing

This will be the setup:
1 server with:
windows server 2003 standard
sql server 2005 standard
30+ clients with:
windows xp pro
sql server express
I will set up a merge replication (pull) and use web synchronization over
https. No active directory will be used.
The clients connect to the replisapi.dll hosted in the servers IIS and
supply a single predifined windows server user (Basic Authentication) to run
the dll. The dll uses a single predefined sql user to manage all sql traffic.
What licenses will be required?
As I understand I will need either 30 sql device cals or a per processor
license (the break of point in my case would be 35 cals).
I will probably also need an Internet Connector license for IIS or 30
windows cals.
Is this correct?
Thanks for the reply.
But doesn't IIS require some sort of a license? For instance if you put up a
webserver using IIS then you need either a processor license or an internet
connector license because you can't predict how many users are actually going
to visit you website at any given time...
I'm assuming my setup would require some sort of license for IIS because of
that.
