Intrusion Detection Weather Clock!

In my insane quest to play with electronics I came across this instructable: Visual Network Threat Level Indicator. I was instantly interested because I could see using this in my work. Intrusion detection is one of those things that is important but once the initial excitement wears off doesn't get closely observed. Who has time?

So, now I'm debating between using Snort or Suricata.

Also, I'm thinking of expanding the Arduino project to include more than just a "threat meter". I'm thinking a little "top report" on a screen.

Lastly, because the Beagle Bone is so cool I'm wondering if I can't get the IDS itself running on this little mini-linux computer and dumping the data to an online drive or, as usual, a database on one of the servers.

Who knows where this will lead, but like all the projects I've listed so far I will provide all the details on what and how far I get with it.
