Hotspot scalability

What are the current numbers being seen as maximum concurrent connections capacity for MT acting as Hotspot alone (no OSPF, no BGP, no wireless cards, no PPPoE server) ?
We are considering both dual-core Xeon PC and RB-1000 for the task, but whas hoping to achieve two/five/ten thousand connections.


What version is more stable for only running Hotspot with MAC-based provisioning, i.e., customer MAC address is used as RADIUS login instead of presenting a web page ?


(sorry for crossposting, but it seems large hotspots are not usual for the general thread)
