Note that in this case the app needs to comply with the LGPL, the
license of the mono runtime: in practice, the individual assemblies need
to be provided. Alternatively, a separate license needs to be issued
that allows the linking: I guess Miguel and/or the ximian/Novell sales
teams can fill in the details if people are interested (note, I'm not a
lawyer, the above is my reading of the license, blah, blah, blah).

* Get the companies that build the obfuscation packages to read
the ECMA spec and fix the bugs in their products that generate
non-standard binaries (or, if they expose a bug in mono, please
file a report in our bugzilla).
* Pay Ximian/Novell to spend the development time needed to get
mono to support the broken binaries that some of the obfuscation
packages generate (or contribute that support).

People disassembling the code is a legal problem and should
be solved with legal means: trying to solve legal problems with
technical solutions is doomed to fail (though of course people are happy
to take your money if that makes you feel better:-).
