Hi, I see what you are trying to find. The idea has been expressed clearly in the following apart from CPSPARQL - http://lsdis.cs.uga.edu/library/download/fp785-anyanwu1.pdf
This approach is based on creating custom indexes on database and thus would scale for large datasets. At present I am working to include this feature as part of Jena. Please let me know if you have already found any such tools; I can use them to compare with my approach. We have the code which can find the paths of arbitrary length give two nodes in a graph. If this is what you want to do, let me know. We can make the tool available to you somehow.
