Hi there,
MIT License ~= X11 License ~= 2-Clause-BSDL ~= ISC License
It is debatable whether 2-Clause BSDL is the same as 3-Clause BSDL,
since international conventions on copyright and many national laws
don't allow the specified promotion anyways.
Still, I don't see your problem. Dojo's License only applies to Dojo, as
it is not copyleft. So anything your developer does can be licensed
under an arbitrary license, so long, as Dojo's copyright header is
preserved for the Dojo-Code involved.
In other words, just tell your developer to not call his app "Dojo
Powerpack X" and he'll be fine.
Of course, this is just personal advice and not legal counsel. If you
want to be sure, consult a lawyer.
Regards,
Hannes
