If you're using an old version of LimeWire with Browse Host (1.8c or below), this ability is still there. The problem is that it will only work about 10% of the time or so. We're currently re-implementing it so that it will work almost all of the time, but this will not be available until the next major LimeWire release, or possibly the one after that.

We definitely agree that it is a very useful feature, though, and it is high on our list of priorities.
