Adding Ethernet is really easy. Either use an Ethernet shield with a Wiznet W5100 or an ENC28J60 board. There is also a mini Ethernet board with a W5100 on it. I have another mini-project running that has 4 ntc thermistors on it using a nano. Originally I used the ENC board but I changed to a mini W5100 board as the ENC used quite a bit of program memory and (as usual!) I was running out of memory. This project also serves up a very basic web page with the temperatures of the 4 sensors.

You could add WiFi quite easily too. Check out the ESP8266 module which has built in WiFi plus lots more.
