I said I was going to leave this thread alone, but I just can't help it....

No.  The legal cannot become illegal.  v2 or later includes v2, so no matter 
what were to happen in a future revision of the GPL, the freedoms you have 
with v2 cannot be taken away.

There is NO risk here.  Please can we stop making stuff up now.
