unfortunately there is a very low limit on this type of card, and its currently no way possible for 100 to be connected at the same time. There seems to be a limit of between 6 and ~15 maybe tops, depending on the card-server upload connection speed. There does seem to be lots of reports of 'drop-outs' and loss of picture even with just 2 or 3 sharing over the net! LAN is best, so no real big commercial advantage, which is good in my view, it just might not interest the eye in the sky.
