It's not that hard, honest. I think Steve's done it for something in  
the past. You just need a bit of basic trig - you omit points until  
the line diverges (say) 2 degrees from the way you're heading, then  
you change course and start again.

(The way Illustrator manages to convert straight line paths into  
simpler beziers, however, is something I'd class as magic but  
fortunately not something OSM has to worry about.)

cheers
Richard
