I've just a little search banner which means people with websites can incorporate a hotspot search into it. It's all hosted by myhotspots so all you need to do is insert a line of code into your page. If you want to find out more, check out the new page on integration.
What could be more exciting for the tech savvy is some XML feeds which means you could actually embed the hotspot data directly into your own websites seamessly. I'll try and get that done over the next day or two.
