I am sorry about that. I am a China person and feel it a little wired cause Emule has already had that function.
I am not a computer engineer and I can not talk about the program in some code level. I'll say something about the phenomenon.
From some of my favorite webs, you can easily find such a thing.(for example http://www.appinn.com/p2psearch/ http://www.iplaysoft...2psearcher.html )
Watch the comments(sorry, they are also in Chinese) and you will find a lot of people that cheer for the software which indicates that they do not use emule well. That goes back to the problem about the popularity of emule(the real one) in China.
By posting such a software in their blog, the owners(they obviously know how things work) show that they care little about emule and P2p softwares.
I should not say that some of our people have no pursuit of beauty. er...
Sorry again for my English.
