> I'm not aware of libmygis' capabilities
libmygis is a work in progress. The author, Jeremy Cole, is subscribed
to this list. I think his plan is to make it support whatever Roadster
needs (at the least), but don't take my word for it. The only problem I
have with libmygis is that I don't know when it'll be ready. :)
I just learned of GDAL. I'd like to look into it.

What would the options be? Like the Wiki hints at, I think it might
make sense to have an Advanced Search dialog at some point. It would
let you specify all parts of your search, just like Google's Advanced

It's all in search_road.c and search_location.c ('location' being the
name for POI in the code). I think the code is pretty well documented,
but I'd be happy to answer any specific questions about it.

I decided to not worry too much about internationalization of the
storage because a) data isn't available yet and b) I didn't know how to
do it. :)
It would be helpful if you could provide as many real-world addressing
examples as possible that don't fit the "STREET, CITY, STATE, COUNTRY"

The GUI is. I'm not so sure about the database. :)

What overhead are you referring to? Memory, disk space, disk access
time, CPU time, or what?
I do have some big problems with the way MySQL's Spatial Extensions
work. The biggest problem is that we incur one disk seek for each road
segment read in. It's also a bit heavy on the on-disk storage size.
I'd be happy to work with you to come up with a new storage scheme!
