Impossible. Who wants to give up their personal information every day/week/month and who wants to verify the information every day/week/month? Unless you are willing to give up access to your trading account, it can't be done - and faxing/PDFing a copy won't cut it if you truly want verification.
The other downside to this is that you fail on one of the most important functions of a HUB - to convert fence sitters into investors.
