Asking for any idea?

Well, i am not sure whether here's axactly the right place, i just want to ask
for any idea as to an "online auction" project. My scenery is as
follows:

Participant should be ready(to be logged into) on the site before a specific
time. Then auction will start at that specific time. All the participant will
own the same greeting site(here a webusercontrol loaded onto a default.aspx) by
turns. When it is one user's turn for a limited period of time, for the rest of
the users the same site(webusercontrol) will be unabled for this period of time.
So i just wonder if there is a kind of class, control, toolkit, method etc to do
this? Or any idea about how to overcome this will be gratefully appreciated.

Thanks...

Please try to use Singleton pattern for implementation.
