Yup, though depending on how you tag the ways, you may need to
customize the rendering rules to get them to render.<br>

Yup. I've done most of it. It needed a little patience, and a little
research, but no magic.<br>

If you don't have too much traffic, you don't need much hardware. You
need a server that has:<br>
- MySQL (for the OSM database)<br>
- Apache (for hosting the slippy map and serving tiles)<br>
- Ruby, Rails, and a couple related items (for running the OSM software)<br>
- Postgres with PostGIS (if you want to run Mapnik)<br>
- Other things (if you want to do other things)<br>
<br>
The point is, the project is in several pieces, so you can set them up
one by one, and they're fairly independent. You can build it up one
piece at a time, only adding on what you need. The above list is not
exhaustive...but basically, one machine running any of the popular
varieties of Linux should be able to run the entire thing relatively
easily, as long as you're not dealing with huge databases and huge
amounts of traffic. Everything you need is either in svn, or free
software available elsewhere (Apache, MySQL, OpenLayers).<br>

<div><font face="Arial" size="2">4) Does this breach what OSM is all
about? Can it be done without stepping on peoples toes? Obviously, this

a specific implementation, I think it would be both helpful and a real
cost saver to a poor community.</font></div>

I can't speak for anyone else, but I wouldn't have a problem with it.
This is what open projects are all about. If you were setting up some
sort of "competitor" to OSM ("Add roads to my map, not theirs!") I'm
sure you'd irritate people, but if you're just leveraging the platform
to serve some niche, I don't see a problem.<br>
