Hi,

And Pyroute and Gosmore and the TIGER-based open source apps that
were there before OSM even existed. And pgrouting, the boost graph
library and graphserver, all of which do routing and pre-date OSM.

I don't believe this will ever work. There are tons of reasons for
implementing an algorithm on your own:
- the programming language might not be the one you want to use
- the software might be written and commented in a (natural) language
that you are not comfortable with
- it might be written on a different intellectual level than you
would do it, and so it is either too primitive or too complex for
your taste
- it might have optimizations that are unnecesasry for your case, and
lack others that you would like to have (e.g. the memory/speed tradeoff)
- you want the satisfaction and learning curve of implementing
something yourself
- ...
Haven't you done the very same yourself - written a routing app
although you could have used existing libraries?
Bye
Frederik
