Google’s “Honeycomb” Version of Android Has a Cloud Syncing Feature, well it will! The App hasn’t actually dropped for everyone just yet(at least not without it Crashing)…See Details.

Apparently A Modder Rooted(Androids Jailbreak) his EVO and worked it out that the cloud syncing is streaming without the memory of an SD card, Tough! So we know when they fix some bugs it will, which will give us access to music on our phone without taking up space!!!
