Sounds like your project overlaps quite a bit with Sjors from GSoC
2008 - http://wiki.openstreetmap.org/wiki/Route_altitude_profiles_SRTM
So you can probably learn a lot from that - especially why looking at
nodes or endpoints of ways isn't great - you miss a lot of detail
(potentially entire hills!) along the way! I don't think Sjors work
ever influenced routing decisions, so there's still work for you to
I would suggest looking into his work, and looking at yours as an
extension of what's gone before.
