Sharing files - free, safe and unlimited

There's an application, to which this post is dedicated - the Java based Qnext. I have all my thumbs up for this one. As described in Wikipedia, Qnext is a p2web application. What does this mean? It means, that Qnext allows you to share everything on your computer (if you want to) - files, photos, music - with a selected group of friends. And what's the best part of it, the friends even do not need to have Qnext installed on their computers; all they have to do is use their webbrowsers, for to reach the shared content.
With Qnext, your computer acts as a server for your friends; there is a big list of waht one can do with Qnext at http://qnext.com/music_streaming.shtml.
Qnext is p2p, which means there are no servers in the middle of the communication between you and your friends (which means no observation (as stated at their website) of the content being shared). And, as the http://qnext.com/faq.shtml claims (the FAQ section of the website of Qnext), logon is highly encrypted and every communication is encrypted at very high level, which is more secure than the standard for online banking. Which apparently should mean it is secure.
So, how do you know how to share with your friends? Qnext provides instant messaging services, which means, that you can share files from your computer with your buddies from ICQ, MSN and some other instant messaging clients; but that's not all of it. You can also enter the e-mail of a buddy you want to share with, and he/she will receive an e-mail with a link directly to the shared files (the so called "zone"). As described in the FAQ section of their website, your computer needs to be turned on, for to allow others to access the files. As good as it seems, qnext is free, multiplatform (java based), which means it runs on everything - Windows, Linux, OSX. One feature I have not tried yet is the video conference, but reviews at the ubuntuforums.org claim, that it works just great. I am not trying to convince anyone to use this; I just wanted to share my enthusiasm about this program, which had made the file sharing so easy (and pretty much secure). For the ordinary person, sitting in front of their computers, thinking about how to send fast this 100mb important files to somebody at the other side of the country, this would be a nice solution.
