Are there any safe (secure) web apps available that will allow you to do P2P sharing? Before anyone asks no i am not referring to pb or anything of that nature, however something that could be a limewire replacement in the web would be most close to what I am seeking.

so, real peer 2 peer will be a bit .. strange with browser-server.
to establish a session between end points (through firewalls) you have to have a central instance which helps to establish the connection. i do not think that this kind of help could be called "webapplication".
anyway, some things look promising:
