You're wrong in your assumption. Both OpenGL and DirectX can render using
hardware acceleration in windowed mode. But when you're in windowed mode,
your current desktop settings affect this. For example, some video cards
will not accelerate OpenGL in 1024x768 with a 32-bit color depth at 75 Hz.
Sometimes, just dropping down to 24-bit color will kick in the acceleration.
There was a program I found out on the net several years ago called Pixel
Format Enumerator and it would tell you if your current desktop mode gave
you Generic (software), MCD, or ICD. It was a C++ program and came with the
source. It would be nice to have a Java equivelant so that we could report
to the user that they are or aren't getting accelerated 3D. But this was a
Windows specific program, working with pixel format descriptors. If I
remember right, pfd's were Windows only and didn't exist in X. I found them
to be too much of a pain and used GLUT.
As for networking, there is an excellent book on the subject called
"Networked Virtual Environments: Design and Implementation"
