Maybe a mybitcoin button could be included using the "other payment " option? There is an option to add html to the item description so its an intriguing idea.....
That is intriguing.
Are there any eBay sellers on here with the experience to tell us if eBay would allow it? If it is a legit option, I'll start a bounty with 100BTC for a developer to take this on in the next couple of weeks.
This is a list of their policies-
Accepted "other payment options"
cash on pickup
bank-to-bank transfer (including by Internet banking)
cash on delivery
bank cheques and personal cheques
any of these online payment services: Allpay.net, Bidpay, Canadian Tire Money, cash2india, CertaPay, Checkfree.com, hyperwallet.com, Moneybookers.com, Nochex.com, Ozpay.biz, Propay.com, XOOM.
Payment methods not permitted on eBay.com.au
Cash through the mail (cash on pickup or delivery is acceptable)
Instant cash transfer services (non-bank, point-to-point cash transfers) such as Western Union or Moneygram
Online or other payment methods not specifically permitted in this policy
“Topping off” a seller’s pre-paid credit card or debit card
hmmm maybe "Online or other payment methods not specifically permitted in this policy" is where bitcoin sits.
