Venforo.com will be launching shortly with a focus on higher end online businesses as their USP because "other business auction sites list 100's of low-value domain names having little interest to today's online entrepreneur"
It seems to be a venture of a Jonathan Berman whom I've not heard of before. His other properties seem to be eQwip.com and tonjon.com which he claims he developed and sold. Neither of those suggest experience in this market but he seems to have invested in custom auction software with Flippa type public commenting and other features. (Why didn't he simply use a Flippa Clone? There are millions of those scripts about!)
