It is not so clear, as I still fail to see how the leaked OGL-1.1 do not acheive that if using my interpretation of "no longer authorized" (That is that the only plain language effect of it is that you cannot use 1.1 OGC in 1.0a publications)
That doesn't give WOTC monopolistic VTT rights, though. VTT competitors would still be able to use your OGL 1.0a license to include your content in a VTT, or you could separately license it for the VTT.
