Playing music from the cloud: nice in theory, crappy in reality

I was hyped up by all the talks about playing music from the cloud.  So I tried 2 different cloud music solution: Amazon Cloud Player and AudioGalaxy.

Amazon Cloud Player doesn't work for iOS devices yet, so I only tried it out on my Android phone (HTC Desire).  I got some music from Amazon, plus uploading some of my own music.  The result of playing it using our company network was pretty terrible.  So was lagging here and there.  So basically, not practical for my use.

AudioGalaxy stream data from my home machine instead of from some cloud storage.  It has both iOS client and the Andriod one.  Using both of them at home, which I assume that it streams music in my LAN instead of using the Internet, is an awesome experience.  I enjoy it so much, and both my Android phone and my iPad was able to handle them smoothly. 

Using AudioGalaxy on the road, on the other hand, is a completely different story.  I tried using the 3G connection to play music, and I found that the iOS app was stuck and not able to get to the player.  Restarting the app, though, seem to solve the problem. 

Using the office network, both the iOS version and the Android version were terrible.

So I guess as for now, using the iPad with 3G connection with AudioGalaxy is my best mobile streaming option so far.
