If you would like to perform similarity queries on your time-series please try simMachines.com (I am the founder)

We offer cyclic time warp search, time warp search and any other metric of pseudo-metric you can come up with :-)

For some domains you will likely need to get a new SLD from a gTLD. For example, a club may need mycoolclub.club in order to remain current or modern. The city of Paris will have a whole new set of TLDs. metro.paris, wine.paris etc... and those would make the related websites look more professional. My startup's technology (simMachines) has been involved in the process of selection of gTLDs and security compliance checks so I can tell you that ICANN has invested a lot in making sure the transition will be safe and fair for everybody.

Regarding space filling curves some implementations would be:

1) http://code.google.com/p/uzaygezen/ (Hilbert)

2) http://www.h2database.com/html/features.html#multi_dimension... (Z-order)

Other space transformations could be employed like the Pyramid technique or the iDistance (http://obsearch.net). Nevertheless, if the "intrinsic dimensionality" of your objects is too high then the curse of dimensionality comes into play and sequential scan might be cheaper. In such a case the Va-file, IQ-Tree or even "sketches" might be the only way to go.
