I beg to differ with your 95% estimate. Practically every time I launch LimeWire, I will see the same ip addresses uploading multiple files from my computer. As a developer, maybe you need to give yourself more credit. Trust me, it works. I would be happy to send you several screenshots of what is quite a common occurence.
I hope you are correct in telling us that the feature will return. I feel slighted after paying for the Pro version upgrade to find that older "defective" versions are browsing at will from me while I would also like the ability to do the same.
