Search using a plug-in! Ohaha!
A bit of a departure from most other file-sharing applications, Ohaha isn't a stand alone client at all, it is a plug-in you can use to turn Internet Explorer into a file-browsing search engine capable of combing Napster, Gnutella and other networks where MP3s and other files are traded. To do this you'll need Microsoft Internet Explorer 5.0 or later.
An open-source project developed by programmers in the Ukraine, Ohaha is clearly an ambitious idea. The Ohaha protocol itself is an attempt to work around the problems experienced by borrowing from both FreeNet and Gnutella, with the goal of creating a decentralized system which is both scalable and lightning fast.

Of all the file-sharing applications you could use, Ohaha may be the simplest and most intuitive. Install Ohaha and Explorer will be modified, giving you a convenient new drop down menu which you can use to search for images, programs, MP3s and the other usual suspects as you surf.
If you're used to the click on demand efficiency of Napster, for the time being you may be disappointed with the results Ohaha produces. That will probably change however, as more people try experimenting with the program.
pluses: Simplicity. Simplicity. And....simplicity. Search for other file types in addition to MP3s.
minuses: Beta. Early stage application, lack of documentation can make using Ohaha a confusing and sometimes disturbing experience. No easy access to important must-have info like ping rate and connection speed. We're guessing however that these are issues that will be fixed sooner rather than later. The tweaking continues at Ohaha hq...
Update: The company plans to release a stand alone client soon. Boosted by curiosity in the open source community, downloads hit 100,000 three days after release.
