Personally, I only drink iced-tea. I just can’t handle bitterness at all, and I prefer cold drinks to hot ones anyway.
I’ve found Peace Tea is the best, but its kinda expensive, so I tend to buy those big tubs of GoodHost IceTea powder and make a jug of the stuff every couple days.
Have you tried setting up WebDAV? From what I know it has local cache support. I use it to access the files on my NAS remotely. Of course, I could be wrong, and my NAS came with it preinstalled so I’m not actually sure how to set it up manually.
