Yup, there have been some developments. Browse to harborfinder.net

I'm slowly processing all 1020+ charts from NOAA and they will all be available soon. harborfinder.net hosts a composite of stitched charts, so some areas (around the edges of charts) may look a little funky depending on the chart. If that area is not to your liking, let me know and I'll fix it. In the next pass of chart processing I'll have a better understanding of bounding polygons around useful areas of a chart.

Here's how to access the data in maemomapper:
Launch maemo mapper on your nokia device, add a new repository (by going to the menu, then maps > manage repositories and clicking New...), give it a name like "NOAA Composite". Change the URL Format to http://www.harborfinder.net/noaa/composed/%d/%d/%d.png. I used the default parameters for the rest of the options.

If that doesn't work, let me know. Note: not all charts are available at this time, so first check harborfinder.net and see if the area you want is available. If not, it will be some time within the next 16 days before your chart is available. Alternatively, you can tell me what region you're in and I can put those charts higher in the queue.
