Yes, the shapefile driver supports editing both the geometry and attributes of 
an existing datasource. Not sure about the state of Ruby bindings to do that 
(they lack a dedicated maintainer), but you could certainly accompish that 
with C, C++, Java, C#, Perl or Python.

Your friends are the Feature.SetField() and Layer.SetFeature() methods.
