as cool as that sounds [no really, i'd love to try to do it], i think i'll stick with a cell phone:
i just got a new one, and it's a flip phone. i found out that the antenna unscrews, and with that off it fits in one of the same small otter boxes that my PSK is in [of course, i went out and bought another for it that same hour].
yeah, yeah, i know gsm cell phones won't work in a life raft in the middle of the atlantic, but hey at least I thought it was cool <img src="images/graemlins/grin.gif" alt="" />
