Release often is a great idea.  It's a real pity that neither Sword
nor BPBible does it, but I wish you success.

Which is why you have to define reasonably carefully what you mean by
agile development, since it can now mean almost anything.  One project
I worked on last year used an "agile" approach characterised by
and it is not at all uncommon to do this (not saying Bibletime will,
just that it pays to be careful).
