Twitter helpdesk question

Io ci provo:

Dear Twitters,

I really appreciated twittering from Steve Jobs keynote and would like to do something similar for a Barcamp to be held in Rome next week, where many Twitters will be attending.

Is it a feature I can implement by myself? Like: I create a new user “Romecamp” and then instruct people there to prefik their messages with “Romecamp:”? Will it work?

Or is it something you must setup from your side?
In any case, I would very much like this to be a standard Twitter feature.

Thanks a lot,
