This is brilliant software. I use it between my heavy duty old PPC DP monster and a couple of macBooks. Very efficient. This version seems to fix a bug whereby I couldn't transfer a small file to the macBook then back again (yes, useful...) Now works fine and fast. Would love to see the networking side of the source purely for interest sake!! For those wanting to use it, go for it, works well in 10.5.2. And interestingly, a very thorough ReadMe document. What are people suggesting as a figure for the donation ware? This is worth it.
