64-bit development of Spur is in progress.  There is a somewhat functional
64-bit Squeak Spur image and a functional Linux 64-bit Stack interpreter.
Coincidentally I'm currently working on an input event processing bug which
only occurs in the real VM.  You may know that the next release of Pharo
(Pharo 6?) is intended to be a Spur release.  Esteban Lorenzano is working
on the Pharo Spur bootstrap.  I am working in Squeak and my priorities are
first, to get the Spur Squeak 64-bit image working fully on the Stack
Interpreter and then to work on an x64 JIT VM.  I expect that by the time
Pharo 6 is ready to release, the 64-bit version will also be ready.

Hope this helps.
