Just found a site with a very similar concept:
http://weendy.comBasically it allows you to do wind reports, take video etc.. from your smartphone. You can link it into your twitter account so that it automatically posts your reports to twitter.
Not dissimilar to what we are trying to do with this idea.
Must admit it looks good, not many reports on there yet (none from near by anyway) but I suppose the value of this is when lots of people use it.
I'll give it a try, but given the conditions recently may take a while before I use it
