DMD license and server installations

[Marco Leise]

I am part of a team that organizes a programming contest that supports  
multiple programming languages. Since there are multiple servers that need  
to be set up, someone in the team placed all source packages for the  
supported languages on our main server, ignorantly assuming that no  
license would prohibit that.
So my question is now what the real story is behind the DMD license and if  
it is probably allowed to do what we do since the installations wont be  
used by real people. (The participants upload source code to the server  
which will compile them.) The version would be 2.054 if that matters.
