This is something that concerns me too as although I am registered in the UK I spend most of my time in Thailand. I would assume though that as ebay only want confirmation when you list something using a different pc to normal that if you are a regular user of auctiva you can still use various computers to access auctiva then they do the listing for you and all looks the same to ebay. Hopefully that is the case???
If you use Auctiva, I think that by-passes ebay's IP check or whatever. And the security key shouldn't matter either, since by generating a Token you have given Auctiva permission to access certain functions of your eBay acct.
