[postgis-users] Interest in open-source road data

I've considered taking the TIGER 2000 data (or, more likely, the 2002
data when it becomes available) and turning it into an open source
road database, with additional characteristics such as one-way street
data, traffic type data, speeds, etc.  The only source for that sort
of data currently are commercial sources, who want a whole lot of
money.  I understand why, of course -- they're highly accurate.

The plan is to begin to populate the line segments in TIGER with this
additional information, keeping track of its source, and to change the
naming method to include an "official" and/or "primary" name for road
segments.  There are a lot of roads that are both I-80 and US Highway
6, for instance, but where they share a line I-80 is probably the more
important.  TIGER often misses this.

I'd start with data for the US roads, but would like to spread it to a
worldwide database, when there is interest for such.

The "funding" plan would be fully free for non-commercial use.
Commercial use would involve some (fairly small) fee, used to maintain
the database itself and to perhaps eventually turn this into a
non-profit organization and hire some real people to maintain it.

The question is, do people here (and I'm starting small :) think this
sort of thing would be useful and successful?
