The easiest thing to do now is to set an OMTextLabeler as an
attribute on each OMGraphic:
OMGraphic.putAttribute(OMGraphicConstants.LABEL, new OMTextLabeler
("street name"));
The labels will be rendered automatically. If you want special
behavior, like scale filtering, you could substitute an extended
OMTextLabeler that will only paint if the scale is a certain value,
or something like that.
The order of the rows in the DBF match the order of the shapes out of
the shape file. If you use the ShapeLayer, you can ask the
OMGraphics for their index (row number) in the app object. There's
an off by one thing going on here, though, so be careful. I keep
forgetting which one starts at 1 and which starts at 0. I think the
index numbers in the OMGraphics start at 1.

I'll have to check on this, but I can't see anything in the code that
handles one way streets.
