Auto-Registration to multiple sites

The script needed would take data (username , password , e-mail , address , etc...) and register with it to multiple sites all at the same time. It has to overcome any obstacles (CAPTCHA or others) in case it runs into them. The list of sites to be registered to will be given once the award will be given. ## Deliverables Script should be written robustly . It should also be flexible enough so when I want to add additional sites in the future it will be easy to do.
