Can a domain be sold by several parties at the same time?
Yes. Although a domain only has one owner maximum at any time, this owner may choose to list her domain with multiple intermediaries. For example, she may choose to sell a domain for $1,000 at GoDaddy, accept open offers from Sedo, and even have it for auction at eBay, all at the same time. UpName works with all these intermediaries to collect all available opportunities for purchasing a domain.
