It's all about mining in pools. Consistent payouts. I've been using wemineltc.com for litecoin, and it's been going pretty well with just a couple GPUs. Not too serious, just playing around, but right now you can do about $100/mo worth of LTC on a single, decent GPU.
I'd love to include it in 3.1, but the majority of the work remains to integrate the markup into the existing templates, plugins, and modules. Hoping to get 3.2 out in record time after 3.1, we're definitely going to hit the ground running. Some other features we're planning to add to 3.2 also.
