An app needs to be sold(given away via coupon) with this for it to be worth very much. I haven't/can't develop for iSeries devices, but have seen it possible to start severs where users can view video streams or upload files.
So, have the app connect to the iFrame server. Find out the internal IP(sent via query, idk) then start the server. Give the user a webspace(iframe.com/username). Now the user can log into their frame remotely and view their camera, change photos, upload content, ssh, whatever AND you could still sell the app. Still not worth a couple $100, but there needs to be some more value added here I think.
