I'm not really understanding the architecture and would appreciate any assistance. I want to set up a live auction system where there are several users receiving bids approved my an admin. I understand how they connect to LS to receive data. But I also need to give them the ability to place bids. When they place bids, they need to go to one admin who is connected to LS waiting for bids. Once he approves the bid, that bid must be sent to all the users who are receiving bids.

1) How can I do this with PHP and/or JavaScript?
2) What is the simplest (non-java & non .NET) approach to this? What woudl all the pieces be?
