Followup to my own posting:

The main problem was how to get the output of a child process.
But using boost.process (Boris Schaeling) I was able to solve it.
Passing the params via environment is not finished yet (ie. the QUERYSTRING stuff or so).
I used something like this:

...
int exec_and_capture(....)
{
   ...
   boost::mutex::scoped_lock scoped_lock(mutex);
   ioservice.reset();
   context ctx;
   ctx.environment = self::get_environment();
   ctx.stdout_behavior = capture_stream();
   child c = mylaunch(Aargs, ctx);
   pistream& is = c.get_stdout();
   sd_in.assign(is.handle().release());
   begin_read();
   ioservice.run();
   status s = c.wait();
   boost::system::error_code ec;
   sd_in.close(ec);
   ...
}
