I found myself refreshing http://dreamcast.online/now/ webpage quite alot and told myself that I should just make a little app that fetchs the data and alerts me if a new player comes online. It's not 100% done and I haven't made the windows/macosx/linux package yet, but they should be ready soon.
Also, I'm using Kazade's data to do this, as he provided the .json file openly, if there's a problem Kazade, please let me know. I'm also using BlueCrab's data from the Sylverant website. Contact me if there's anything!

I've had a couple of time where there was more than 10 player and perhaps a scrolling function would be nice!
