Thanks guys...i did realize the limitations with MAC/IP.

So, to give you a little bit more without divulging my business completely, the business i am launching will be almost like "One-person-one-vote" voting system. I don't think the app fails if people open multiple ids as i have other means of validating uniqueness of an account... but, i am trying to see how best i can identify users multiple accounts through other means(MAC/IP etc), and have a procedure of identifying, alerting users, and deleting their multiple (duplicate) accounts.

It's almost like i can open multiple accounts and vote for democrats, if i want to influence democrats to power. I am trying a voting platform that will enable each user to cast their vote - only once on an issue.

Any help in your suggestions from technology perspective would be highly appreciated?

Hi,
I am launching a site, which has a pre-requisite of having each member as a unique user. That means, no user ideally should have multiple accounts. I was hoping that i could track users MAC id only during registration process with a software that might be availble.

Is this a possible solution, or you would recommend something else? I know IP tracking is easy but has no relevance to unique user here.

Any thoughts would be highly appreciated.
Thx.
