Do you approve of the re-licensing of JSon.NET?

Hi everyone,

today I am working on Mono 2.0 Debian package and noticed that JSON.NET
was relicensed from Creative Common to MIT/X11, which is very nice. I
was trying to verify how the relicensing was done, which would be either
re-sync code from upstream as the latest releases are MIT/X11 already
or ask all copyright holders for permission to relicense the current

The changelog revealed:
2008-05-20  Jb Evain  <jbevain at novell.com>

        *.cs: all files from JSon.NET are now re-licensed under the
        MIT/X11 license, thanks to his author James Newton-King
        for relicensing them.

Which made me worrying as James Newton-King is not the only copyright
holder of the code:
grep "Copyright" -r ./mcs/class/System.Web.Extensions/System.Web.Script.Serialization/JSON/ | cut -f2 -d ':' | sort | uniq
// Copyright (c) 2007 James Newton-King
// Copyright 2007 Konstantin Triger <kostat at mainsoft.com>

I asked Jb on IRC if he explicitly asked Konstantin Triger if he agreed
on the re-license but he said he hadn't. Thus I am bringing up this
issue on this mailing list.
