The suggested Title ID's are as follows:
0001000148434650 (PAL)
0001000148434645 (NTSC-U)
000100014843464A (NTSC-J)
In so far as creating a wad, NUS Downloader v1 will definitely do so when using any of the aforementioned Title ID's. What isn't clear is whether or not there are any specific IOS files required in order for the Wii Speak Channel 2.0 channel to work (that weren't also required for the previous version).
