xnap is a great filesharing app and even works on most firewalled university connections. next to the gnutella network, i've found it to be the best around. as for the interface, the "adaptive" theme or whatever it's called looks a lot like osx, enough to be very usable. the developers are working on this program on their own time and with no compensation and still people bitch that the interface does not look exactly as they want it. why dont you download the sourcecode and build a native version if it's so important to you? we're lucky that we can run it, you have to remember that not many people use osx and if you're going to bitch about how a first rate program does not look the way you want it to, you should not be surprised that things like kazaa, bearshare, directconnect and the rest aren't on our platform. it's a 5 star program with a very good interface for an osx java app. i'd like to see another pure java app (not cocoa java) with a better osx adaptive interface.
