$ lipo -info mono
Non-fat file: mono is architecture: i386

I expect result like this (from Firefox):
$ lipo -info firefox
Architectures in the fat file: firefox are: x86_64 i386

Binaries being universal rather than 32bit only can make native libraries related stuff much easier.

For example, I once tried using Tao to do game programming. I compiled some necessary native libraries without additional tune so they are 64bit. I spent much time before I realized that 32bit Mono stuff can never load 64bit dynamic libraries.

Thank you in advance.

We currently do not have plans to ship a 64 bit Mono, since our major UI libraries (MonoMac, Gtk+ and Winforms) are not 64-bit ready.

Fixing those is a project on its own, so I will be clsoing this bug as there is not much we will do until we fix the others first.

64bit is the future. 
Though current mobile platforms, where you seems most interested in now, are still 32bit.

If you don't have a meta bug for 64bit cleanness of Mono, why don't you change its content and keep this one open.
if you do have one, Mark as Duplicate.

Because that is not how I do things.
