Do you know about RRDTool? There are ruby bindings for it, too.

I'm using it to do more or less what you say: remote systems measure 
temperature and other variables, and fire the data to a server (UDP, not 
TCP, though). The server collects it into RRDs (Round Robin Databases), 
and there are some simple CGI scripts (not ruby, but RRDTool's own mini 
scripting language) to display the data according to user inputs (time 
ranges etc).

Of course, if you're doing this to learn Rails, maybe you want to do it 
the hard way :) ....
