[Mono-list] mono support for C++

[George Birbilis]

make a .NET webservice for a MS VC++ compiler running on a Windows machine
and compile for .NET (IL) target. Resulting code should also run on mono (I
hope)

cons:
1) user has to trust your service to submit their code
2) can't use that offline
3) need highspeed connection if you rebuild too often
4) may need to have a server farm if your service becomes too popular

other idea (at least on Linux/Intel machines) might be WINE etc. in
combination with MSVC++ compiler with .net target

or a C++ to C# transcoder (OK, maybe without support for multiple 
inheritance)
