Certainly it can be changed.

I'm really surprised that it is called once for every verse. The pattern 
that BibleDesktop uses is to gather all the requested verses into a 
buffer and call the stylesheet once on it. Is it that each verse is 
indexed and thus built separately in the GoBible module?

There is a lot of other repeated overhead that happens that we have 
considered too small given the expected use pattern.

This too can change.

Would you open a "bug" in Jira (www.crosswire.org/bugs) against JSword? 
Just one for both of these would be fine. If you want to work up a patch 
for it, appending it to the issue, please make yourself the issue owner. 
Otherwise assign it to me.

Many thanks,
