Interesting. I knew some emulators provided replacement drivers to allow
the OS in the emulated environment to better interact with the emulator,
but I must admit I didn't realise the replacement drivers had developed
as far as providing (in this case) DPI on incoming network packets.

It would be interesting to read the documentation for a emulator which
provides this support and see what the drivers are now capable of doing.
Do you have a example to hand ?

Thanks,

Simon.
