For the amount of data you are talking about (100MB per day), you can probably get away with just triggers on the DB A tables that insert into DB B.

The streams option always bothers me, personally. We used it to migrate a fairly large database last year on what was then from AIX single node to Linux RAC, and we had all kinds of weird issues, about 20 one-offs to apply, you name it. We were beginners with streams, so I'm sure we were inefficient in how we set it up, but I wouldn't call it "easy" to configure, especially with database that generate a lot of redo.
