Sometimes, I'd really like to be able to just retrieve a file and continue working with it. No need to safe it in the filesystem, if the file is smaller than 100 Byte. I currently really miss the option to do that, because I want to retrieve the ftp-masters/volatile-masters current date from mirrors. Well, probably I'll be back to my ugly script soon again that retrieves the file somewhere in a temporary place, and cats it from there.

Update The main thing of this entry is the tiny rsync in the URL. With http and ftp, it's trivial. wget and lynx support it out of the box, and also all the major scripting languages. Just rsync is unsupported - which is however what I need.
