Geoff, they're still on Ebay. I think your search came up short due to a typo--it's "Peacefulpigs." However, I'm sad to report that they are not currently offering any patches. I may still have their email address if you can't reach them through Ebay's message system. Just let me know.
I must say Peacefulpigs generated a lot of controversy in certain circles, being hated on USAFPatches.com, but then again they offered a great selection of Vietnam War-era patch designs that if not collectible were at least suitable for those wishing to approximate "the look" without spending the time and money required to track down original patches. I have a bunch of their patches in my stockpile, but I've also been lucky to have found a fair number of originals so I'm rather undecided regarding what to do with the PP items.
Here's a pic of my PP examples mixed in with a few patches from other sources. At first I mistakenly assumed the 8th TFW patch was a repro based on the "Made in Japan" label on the back, but I have since learned that they made plenty of these in Japan during the war. Good thing I didn't sell it!
And some originals:
