Definitely! You could try porting the sword lib to Psion.

Definitely interested too.
But IMO for bibles there are different ways of storing information in the 
index, esp. using bitmaps for large search results (1bit = 1verse) that can 
easily be combined with logical operators (AND, OR etc...).
This will need some discussion and input from the others, but that is 
something you could work on! But let's start with the compression. Imo sword 
has an architecture open for different compression algorithms, so integrating 
your algorithm should be rather easy...

Because sword does run on different architectures you cannot use assembler 
code. Well written c++ code and a good compiler should be almost as fast...
