Not sure if lectionaries have been retrofitted for digital consumption as easily as Bibles have. But its worth asking a few folks if this has been done. Its most probably not something left to the free software/open source movement to do easily I'm sure. And there are different lectionaries and sacramentals depending on one's denomination. If the effort has already been started here, then maybe Katana - and free software/open source in general - could prove to be quite beneficial to those parts of the Body.

I'll poke a few folks and see if there anything that could be found.

EDIT/ADD: to any of you with lectionaries near your fingers, would you mind sharing the publisher's name (either PM or here directly). It would be those persons to speak to for this.

To the developers: we've talked about making some closed-source modules, can any of you PM me a basic schema (or two) that you were thinking about for this. I'll include a high-level talk of this to those persons that I reach out so that they understand the cost/benefit for them in doing this.
