>>just very hard and not worth it

>>some special wifi thingy, since IDK if you can send stuff to PTC over normal wifi

If it's not worth the time, how do you expect it to work with this?

Yes, in a way, you would need a "special wifi thingy." As far as I know the DSi's wireless communications protocols haven't been reverse-engineered to the point where you could set up your router to take the messages. Then like you said you would have to know how the software (PTC) deals with the information sent with SEND/RECVFILE and you'd probably have to send a confirmation signal, etc. Once you got that, you would have to figure out how to work around the limitations of SENDFILE (triple confirmation, long send times, user control...) to make it work effectively.

(Actually, it looks like someone has gotten the DS to converse with an external unit, but with a specific series of WiFi card.)
