I think that the best solution is the binfmt feature with the wrapper
that exists with Debian packages at:

http://www.debianplanet.org/mono/dists/unstable/main/source/admin/

If you want use it with Big endian machines, you should apply a patch
(http://carlos.pemas.net/debian/mono/binfmt-detector-cli.c.diff)

It works really good and lets you use wine also, it reads the .exe file
headers and check if it's a .net executable.

This way you just execute: ./my-cool-mono-application.exe and it works
without the need of any wrapper.

Cheers.
