Depends on what you mean as "very low traffic".
Your 1st problem will be your IP address. If your cable provider is willing to give you a static IP then you will be able to have a very low traffic web site. If your provider is using DHCP, then you have problems. Your IP address will be subject to change.
You also have to be carefull of content. The upsteam speed of your cable is slower than the downstream speed.
If you have too much upsteam traffic your provider may get upset and declare you a commercial site.
