In the Data Sheet, they make specific mention of CCA supporting up to 10 AP's:
Cisco Configuration Assistant simplifies the task of configuring and managing the AP 541N as well as the entire Cisco Smart Business Communication System. Cisco Configuration Assistant supports up to 10 Access Points
So I wonder if this limitation is purely software, and that if configured via the web interface, that more than 10 devices can be used?
As far as the 100 users go, that is simply the "advisable" range for the SMB and SMB Pro products. When you get into larger user bases, you are expected to get into Cisco's regular offerings.
