GLBSE Security

[Anth0n]

Suppose I set up GLBSE in a virtual machine and buy some shares of a company. Is there anything stopping me from buying shares, copying the virtual machine 100 times, and selling the shares on all of the VMs? My guess is that each user is assigned a value to prevent this, but I just want to be sure.

All your VM would store is a userID reference that authenticates you to a folio of shares and a balance that is on the GLBSE servers. Nope, double selling will not work.

The client download is, as far as I can tell, not much more than a makeshift frontend. Your shares/deposited BTC are on the exchange server, so any transaction you do from any client will be final.
