If you're doing item-based recommendation, doesn't it make sense to use multiple recommenders, one per category? This should reduce your training time, instead of training on all items then throwing away most of your results.
If it was user-based recommendation I could see the value in finding similar users across multiple categories, then paring down the recommendations afterwards.
