Upon skimming, it looks like it still retains some clauses like: "The name of Your Product (or of Your modified version of This Product) must not contain the name TrueCrypt [...] nor any other names confusingly similar to the name TrueCrypt" and "All graphics contained in This Product (logos, icons, etc.) must be removed from Your Product (or from Your modified version of This Product) and from any associated materials."
...but that actually doesn't seem all that insurmountable. Hm...
TrueCrypt 7.1a - the one with the actual functionality - wasn't released under this license. It was released under the earlier one. And I don't think it allows for this version or later ala GPL. I'm not sure of this, though.
