What could this router possibly do other than it's intended use?
What kind of other "programs" would be useful or just-fur-fun for this?
One idea:
An integrated LAN MONITOR into the router. A program that would graphically show the traffic on the LAN/WAN and be able to log in remotely to see the data?
Maybe graphically is asking too much with so little memory.. how about text a text based one? And that can be set to store the data on a local machine. An option for max log size so as to not fill up one's hdd.
I'm not a programmer in this language yet.....but I'll get there with LOTS of help. I probably have more interest in it that I should, but I'm going to give it a shot. If one of you guys beat me to the punch....that's okay.
You mean like this? Should be possible with Tomato firmware. Sorry for the poor quality, have to resize to make it fit the forum.
You can see it here at http://www.polarcloud.com/v/scbwm.htm
As has been pointed out, Tomato already does pretty graphs. DD-WRT v24 also has a traffic monitor that shows graphs of traffic in/out on the LAN, WAN, and wireless on individual graphs. You can also add BW logging to DD-WRT:

However, for proper monitoring, the router should generate and collect SNMP data. The data collection programs and graphing are best done by a dedicated management PC. I use MRTG, PRTG, RRDTool, and various other SNMP apps for data collection and graphing.

I've also installed the MRTG data collector in the router, but that requires more RAM than most routers have available or installing an SD memory card which requires soldering and butchery.
The big problem with monitoring is that many of the wireless chip level numbers are not easily available. Important items such as the wireless error and retransmission rates, are not available. The supplied OID's are adequate for layer 3 (IP) monitoring, but not layer 2 (MAC).
Incidentally, before suggesting any more features, you might want to look at the DD-WRT tutorials section, which details some of the more obscure and exotic features.
