Thanks Gregl! Right now I like using it with my Chromecast. On my server, I have a little script where I can associate Youtube videos to tag ID's. So when I press one, that Youtube video associated with that tag is sent right to Chromecast and begins playing. When my son is a little older, I can stick the tags on toys and books so when he touches them to the thing, it could play his favourite videos associated with those objects too. I also have a client whose office is really into ping-pong and I'll make one for them soon. Maybe they can use it to keep score or something. They already made a little web-app for that.
