Q: ideal representation for network (TIGER/line) data?

Hi all,
I noticed the recent message about Census/TIGER files. We too
are going to be generating maps from tiger line files. Our
proposed solution is to parse the relevant files using perl, then
spit out a network representation for display in Openmap. In the
past we've used other programs to create shape files, but we are
going for a complete opensouce solution here.

My question pertains to trying to optimize the rendering in Openmap.
Before we used the .ssx and .shp files and didn't think about it.
Now that we are thinking, is there some optimal format that
we should copy so as to create a layer that is easily rendered?

I noticed that the shp and ssx files are binary. does this help
with rendering speed?
