I didn't say it is easy, it just shouldn't be harder than, say, doing
it in C++ (even if you will find more example programs in C++).

Well, I can say it's definitely not going to be that easy. You, too
will soon learn to apprecate how much OPC sucks ;-). I did implement
an OPC client library in my previous job (after which OPC was actually
quite usable), but it's proprietary.

Probably. Industrial automation is not necessarily "interesting" if
you are not working there. Open industrial automation infrastructure
would be an extremely interesting avenue for academic research and
subsequent lucrative consulting, though...
