This is neat stuff but they have one big problem. To handle the home firewall traversal problem they developed their own protocol which requires a browser plugin. The way you navigate to their tiny servers is thru links like this:<p>nabto://test.nabto.net<p>If you browse to a Nabto device with <a href="http://" rel="nofollow">http://</a> instead it displays a page to download the plugin but with most browsers now ditching the protocol prefix I think this is going to be a VERY hard sell.
