64-bit Linux Emulation on AMD64?

[alex]

Hello,

I've got a fresh new 4.0/AMD64 system installed, and after sitting down 
to add Linux binary compatibility, I see that it apparently doesn't 
exist on this platform. After some archive digging, it doesn't appear 
that the idea has been thoroughly discussed, especially since adding 
32-bit Linux binary support would be difficult at best 
(http://marc.theaimsgroup.com/?l=openbsd-misc&m=109036873227847&w=2).

Since I'm not exactly familiar with what exactly makes Linux 
compatibility work behind the scenes, I apologize if this is a dumb 
question...but would it be feasible to add support for Linux/AMD64 
binaries on OpenBSD/AMD64? It seems like this would eliminate the 
problem of 32-to-64 bit conversions/wackiness, though I wouldn't be 
surprised if other nasty problems were lurking under the hood.

If this is within the realm of possibility, I'd be interested in 
working to make it a reality. Given my lack of experience, I could 
probably be more helpful as a tester for someone else who was 
attempting to implement this...but if there's no one out there 
interested in working on a project like this, I'd be willing to take a 
stab at it myself, especially if whoever is responsible for i386 Linux 
compatibility was willing to speak with me regarding at least the 
basics of what would be necessary.
