Possible project

Hello All, I started by looking for a Tone & Probe (aka Fox & Hound) set that I could build for myself. Something similar to this...http://www.amazon.com/Fluke-Networks-26000900-PRO3000-Analog/dp/B000FTADX0/ref=pd_cp_hi_0.

Well on several of the electronics boards that I started reading I repeatedly saw references to this wondrous little gadget/tool called an Arduino. Ok, i'm hooked on the concept and have a starter kit on its way. Now I know that it will take some time and I'll have to work my way up the learning curve, but now instead of the simple tone & probe set I was wondering if Arduino would be a good basis for a home-built version of a full fledged lan tester. Something like...http://www.amazon.com/Fluke-Networks-MS2-100-MicroScanner2-Verifier/dp/B000QJ3G42/ref=sr_1_1?ie=UTF8&qid=1345571232&sr=8-1&keywords=fluke+lan+tester.

I would probably trim a few bells and whistles but incorporating the tone/probe, wire mapping, distance to fault, etc would be a great gadget to build. Thoughts? Suggestions?

It might work, but you see where the Lan tester says "Detects today?s media services, including 10/100/1000 Ethernet, POTS, and PoE", well ....

... change that to read maybe 50,000 bps instead of 100,000,000 bps when using the Arduino, ie .05 Ethernet.
