dealing with paypal is not an easy task, i believe that paypal should be requiring documents that these companies are not the time to deliver, i saw this on the paypal site:
Service Requiring Pre-Approval
Airlines and scheduled or non-scheduled charters/jets/air taxi operators; collecting donations as a charity or non-profit organization; dealing in jewels, precious metals and stones; acting as a money transmitter or selling stored value cards; selling stocks, bonds, securities, options, futures (forex) or an investment interest in any entity or property; or providing escrow services.
I think that for the type of service that VIRWOX offers, they will have to have many documents so that paypal accepts that they use paypal
