Virtual JTAG is what you'd use to "replace Signaltap". This gives you access to the JTAG interface so you can create your own debugging logic that can be accessed via JTAG. USB is not JTAG. If you're referring to building your own USB-Blaster (JTAG to USB converter), you can look at recent Altera dev kits that have the USB Blaster hardware on the board (instead of a separate "pod" that attaches to the FPGAs 10 pin JTAG connection).
