Is this what you're talking about: http://tunnel.bloodbird.com/
If so and if I understand correctly, this tool acts as a client for your PSP to connect with other people.
It should be possible to use JPCSP with this method too, but it would be quite complicated, since the tool relies on USB connection.

Yet, that tool relies on USB connection. But it also support you use wireless lan card If you wireless lan card support PSP XLine Mode.

There are another client for PSP to connect with other people. It is name MengZone,
and it support PSP game with Dynamic SSID.
