Communication Through Scrying.. Options

Here's a (yet another) random theory my mind has been going over a bit.
Some spells I've seen employ scrying to physically affect whoever is on the other side; carving into water, for instance, among other things. I've been wondering if anyone thinks it would be possible to communicate through scrying methods... using fire or water or crystals or whatever as a mystical telephone of some sort. There have been a number of references in literature about wizards communicating through fire (and yes, I do realize I'm talking about literature, but groove with me). I don't mean, necessarily, talking through a medium like looking through a window... but perhaps conveying thoughts or ideas to the person on the other side, maybe words within your mind if you've got some clairaudience happening. Just some scattered thoughts, any ideas appreciated. Thanks:)
