What software can you use to push presentations and quizzes to Blackberry?

Has any one pushed presentations and quizzes to Blackberries? I was just given a project that I'm not too familiar with and I need all the help I can get. I need to implementation mobile learning and the audience I'm targeting are Blackberry users. I wanted to know if any one has done this before and what software have you used or if you can point me in the right direction.

I've been looking into Hot Lava Software but they charge a monthly fee per user and I'm trying to avoid monthly fees if possible.

I really appreciate any help at this point,

Cindy
