LinuxCNC Post-processor for MasterCAM X4?

First post, so please go easy!

Has there been any further developments in creating / establishing a recommended post-processor for LinuxCNC in MasterCAM X4?

From what I can find, last signs of a post-processor for MasterCAM were in 2010, with user Mike_Eitel posting some files. (Thanks, Mike!)

Have there been any updates to these posts? Any users with MasterCAM and LinuxCNC, can you say how well the existing posts function?

Thanks!
