send jpeg thru udp

hi,

i need to send jpeg images to the device,
it works using code pasted below, but it is win specific
(and outside max),
im wondering if its possible using java or tweaking jit.broadcast
(although i couldn`t get it to work).

btw: how i can adapt it for terminal use in os x?
i`ll be grateful if someone can have a look,

thanks,
wojciech
