Thinking the same and with this climate change (or lack thereof depending upon who you believe, ahem), I think they're only gonna be fewer and farther in between in the future.
Would it be possible to add a short pigtail cord to the charging port on the earpiece and tuck it in the helmet when not needed, or do they use some proprietary connector?
Very little info...

Not that it can't happen on skis, but I get the impression that falling while boarding has an increased chance of that whiplash head smack, especially if/when you catch a downhill heel-side edge.
