Wow that's quite a concept. To me that idea smacks of some unknown type of energy which has the potential of being converted into regular mass. However, it would seem to me complex mass would be impossible because as the particle's mass oscillated between the real and complex states its speed would likewise be respectively slower and then faster than c. Heh, imagine the shock waves from something breaking the light barrier a couple billion times per second, and the energy dumped into entropy. I don't think a particle with complex mass would make it very far. More like a one way ride...
Pure imaginary mass (the tachyon) is pretty neat to think about though. What kind of state could mass be in its "potential" form? The old E=mc^2 certainly implies that you can convert energy into mass, but I'm not aware of anybody who has created mass out of pure energy yet.
I still have a Netwinder. I spent quite a bit of effort porting the system to Gentoo ARM softfloat, although at the end of the day, it really hasn't aged well. The 275MHz ARMv4l seems a bit pokey now but it can run a bare-bones xorg system with a lightweight window manager. Prior to my porting effort, you had to use hard-float glibc which would trigger an interrupt and the kernel fpu emulator would handle the call. I submitted some patches upstream vs gcc but I have no idea if anybody ever did anything with them, for all I know I have the only softfloat-linux Netwinder in existence.
I was able to compile the Hercules IBM Mainframe Emulator for my OMAP3 Beagleboard, and guess what.. it works.
Dear Descendant,
Please send me an email from the future describing how I can solve my current financial distress.
P.S. I will set up a trust fund for you if you do this.
Regards,
Your Ancestor
