allow people to add their facebook to my seesmic.com account

I am using [login to view URL] to post to facebook for many accounts. seesmic lets me log into seesmic and then add more facebook accounts. i would like to allow other people to add their facebook accounts to my seesmic account, but i dont want them to log into my seesmic account. So my solution that i want you to do is make a website program that when someone comes to this web page it will ask them what type of account they want to add, and allow them to select from a list of available accounts facebook, twitter, etc, it will then log into my [login to view URL] account without letting the person have access to my seesmic account or password, then it will click: settings, add a new account, and then click on the type of account the person selected, facebook, twitter, etc. Then when the facebook login page is called up where the person can connect to facebook, login and allow seesmic to "Log in to use your Facebook account with Seesmic." it will call up and show that page to the person so that he can login by himself. This solution enables him to add his facebook account to my [login to view URL] account without him knowing my seesmic password or having control of my account, and it allows me to have his facebook account added to my seesmic account without me seeing his facebook password or having control over his facebook account. This is a simple program that should cost between 50 - 100 $
