How many listeners can my hardware handle?

[dbp653]

I have a XP PC with 100 mb/s networking card. My ISP is giving me more than 100 mb/s upstream available to me. In theory what is the maximum number of Shoutcast users that I can service with this one PC?

I want to stream a popular college football game, and the athletics dept. tells me to figure for up to 2000 simultaneous stream users.

For example a 24 kb/s stream times 2000 users is 48 mb/s bandwidth needed? Figuring a 50% saturation on my equipment, allowing for reconnects and other unexpected things.

Or am I dreaming, what am I not figuring into this to service this many of users? i.e Hardware bottlenecks.

Does anybody have any experience in serving this many users?

I need any perspective you may have.

Thank you,
Darren
