It's a pretty new thing, only latest yum such as in Fedora 7 supports it 
and now apt-rpm. The advantages are memory usage savings and random access 
speed, both improve *enormously* with sqlite:

On my F7 x86_64 system, 3.91 doing a full cache rebuild tops at around 
222MB RES with xml metadata and around 33MB with sqlite. Random access (to 
the actual package indexs, such as when calculating download and disk 
usage size during install/upgrade) speed increase is of similar order of 
magnitude, probably even bigger. The price is slightly larger index 
downloads, but well worth the benefits IMHO.

Probably not hard, just haven't gotten around to it :)
