2. PCI host<->guest proxy 2. Plugin architecture
2.1 The plugin architecture can be reworked if we want to support
multiple similar devices like seral net or vga cards.
We currently have two "types" of plugins: "core" and "optional".
Maybe we could add "classes" of plugins. The current version of
Bochs supports the classes "display_library" and "io_device".
New classes can be "config_interface", "net_lowlevel" and
"sound_lowlevel"

Bochs VGA plugin for example will be real plugin. I mean that replacement
of plugin dll in already compiled Bochs will replace Bochs VGA card and
the new card will be detected automatically.
This will allow for example developing of plugins separately from Bochs.
