winXP USB key authentication

[Gavin Swanson <s7726 () yahoo com>]

Is there a way to use a regular USB storage key to login to a winXP pro box. I'm just looking to use it on my home 
system. I would like to be able to walk up to the system and insert the key into the front USB port, thus causing 
windows to log me in, without typing a password. i would then like to be able to either logout or lock the workstation 
simply by removing the key. Is this possible using free utilities?

Thanks
