This is highly unlikely - eBay will not spend resources to develop this... however you have extensions / add-ons for all major browsers.

Given that we have now authorised Ebay to specifically allow you to place our bids on our behalf, could you please suggest that when we log in to ebay, it recognises that we have an authorised snipe service and where there are the buttons to Buy/Bid/Watch that there is another button, 'Snipe' that becomes visible ONLY because there is valid authorisation.. having a generic button, will allow ebay, in future, to apply code to other snipe services, if and when they gain the same level of interface with ebay, without changing the physical button... when clicked, the button automatically opens a browser to Gixen and places the item reference number in the box. In the event of multiple snipe services being authorised on the account, the 'snipe' button would defer to a choice page, in the first instance, and then on as above.
Whether ebay can log in to Gixen on my behalf, or Gixen can retain the item ID whilst I log in, is a fine detail only you can work out with Ebay

have a great time... whether that ends up as a mask to mask, or virtual event, hope you have a good and productive time.
