Instant802 offers manufacturers mass-profile possibility for access points: Instant802 makes the software for service providers and manufacturers that runs their APs. For instance, the Gateway AP series that I have praised in the past uses Instant802 firmware. They've released an Enterprise Managed AP (EMAP) platform which allows many APs to be configured as if they were a single AP. This is a fascinating way to sidestep large-scale management through a cluster profile, because the platform handles load balancing, beacon assignment (up to four SSID names per AP), and channel selection. Call it a plug-and-play enterprise solution.
