Does any eBay software let you use e-junkie with it for digital items?

[Twocoolt]

I have wanted to automate my accounts so once a buyer pays for the digital item as a buy it now they get to download the product after checkout. I have found e-junkie but they don't have features like auto-feedback or to show the item as sent. Any suggestions or is there a way I can use e-junkie with Auctiva or Antlisting? Any ideas appreciated. Thanks.
