I am having an art show at my house and would love to collate technology with this event. People will bid on pieces of art and I would like this to be via an application I made. I would like it to: - Store a person's contact info and name - Save their bid history - Be live updating - Display the action on a screen (preferably a laptop; bigger) My questions are this: -- Is there a name for this type of service or feature? -- Can I accomplish this without making a separate program for a laptop (or do the laptop need to act as a server)? -- Would it be easier to make a website that facilitates these features? I appreciate any help!
