> Also I would like to know how you would attach a debugger to a stack that contained, among others, ASM/C-code running on an embedded device on the other side of the world, some MFC/C code on a gateway windows computer, perl scripts running god knows where and a PL/SQL bundle on an Oracle server in another country and some Java logic on a different server. That sounds incredibly brittle. But each of these components should be debuggable individually and have a well defined interface.
