Dear Sir,
I have two things in my mind :
(1) If you want to have such a software that can be used for sharing between two local computers for internet purpose than i have one good software that works great without any problem. No virus nothhing.
(2) I have one more software that will be helpful for downloading, searching of any file, pictures,application,music,video etc., from the computers of particular group who also uses this software.
If you want above or may be other than above software than please inform me about it.
