you can piece it together, i think. xantech makes an ip to rs232. the unit keeps an ip address on the network. if you combine this with the rs232 to ir unit, that could probably do it with some coding. it would be slick if the xantech unit provided browser interface, then just point your pda at the right url. I expect we will see an ip to ir from xantech someday. and what i wouldn't give to be able to tunnel ir through ip!!!
