sleep fm would be better if they made a decent video (browser area only), removed the stylesheet (the interface is horrible) and lost the sleep fm 'loves you' type impression. Its a utility.
It could be useful if they streamlined it and marketed it without the corn :P
I don't run my own installation (used the hosted one for about a year) but have seen friends upgrades go not so smoothly. In keeping with various updates I'd say it'd take a bit of time.

I like the pipes idea alot though, can see it's use.
