I wanted to know if it could be possible to put logos to the player via Ethernet like Hijack ?

This is not currently in the logoeditor feature set and there are no plans to add it.

If Mark made a magical something in /proc equivalent to empeg_kernel, but corresponding to a different address range, it would be trivial to upload logos using ftp (and employing M$-supplied ftp client using command file from VB would also be a simple, if somewhat inelegant solution - in the case that a free ftp component/control can't be found).
