I was wondering if there are any alternatives to pgRouting tools.
Thinking about it for a bit, I think the only alternative is to use R or RPY to do the analysis.
Basically I'm trying to solve routing problems based on nonPostGIS databases. As most of my data is actually stored in a different format; however, it's not to hard to convert. I'm finding that pgRouting to my dumb silly brain is difficult to implement. So perhaps a non-database solution that I can easily tweak would be ideal for me

[Edit: this has been superseded by nx_spatial which is available from pypi (easy_install nx_spatial). Importing shapefiles is now standard in networkx 1.4]
I've been kind of disappointed by the lack of geometric network tools in ESRI's Python GP API, so I wrote up something that loads Shapefiles and Feature Classes into networkx directional graphs (DiGraphs).
It is still a work in progress, but it might be an okay starting off point for something that can help with your problem.

Samples:
Network is inherits from networkx.DiGraph, so all of that functionality is available.
