I think logos should start a public domain group. I was looking on finding the best way to get public domain books. I came across a website that charges $100.00 membership fee and you can download as many public domain books as you want. These books come in a variety of formats, so you can put them into the pbb.
I would be really cool if logos started a similar group. With enough members, the membership fee can fund the production of these public domain books. This would also bring in the "low end" customers seeing as they can get resources and use the logos engine. Eventually those who use logos will want to upgrade their library to something more suitable for study and purchase base packages and so on.
It seems like a win for those who are already active in the community pricing, and draw those who are not in. For those who are use logos currently, and for those who do not.
I don't know how much a logos employ makes but if we get 400 users that pay the membership fee. We can pay someone 40,000 a year to publish these public domain books. Also the public domain members we can help publish these titles also.
Just a thought, it seems like a win win for everyone.
