Yes, native applications with access to main's argv[0] can achieve
it easily under Linux, but managed apps simply cannot access this
location. There is also no way that I know of to get a ptr to
this memory location from a native library, so p/invoke won't
help either.

You may want to file an enhancement request with Mono's bugzilla
stating that you wish a facility for *dynamically* changing
the process name.
