The Spread license is very similar to the Apache 1.1 license, which can
be summarized as "BSD + advertising clause," so it isn't GPL compatible.

This probably isn't an issue, as the Mono class libraries are MIT/X11,
and thus could safely use the Spread code, though it would make
distribution and advertising very annoying and would prevent
System.Messaging from being Free software....

D-BUS is dual-licensed under the Academic Free License and GPL 2, so it
avoids any advertising issues.  (This is from dbus-0.21.tar.gz.)

However, last I knew D-BUS only works locally, and not across hosts,
which makes it of limited use for a general System.Messaging
architecture.  Furthermore, it's limited to Unix systems (IIRC), which
would limit portability to Windows.
