Quickly sharing temporary snippets between developers

I am looking for a quick way to share code snippets between developers. Visual studio allows you to use a file share as a repository for snippets, but the VS Snippet manager seems more oriented towards "permanent" snippets you want to keep around. I'm just looking for a good way to send a block of code to another developer to look at, or copy into their code.

Instant messengers tend to have character limits and don't really retain formatting well. I could use something like pastebin, but I really don't want to expose this code to others potentially for non-disclosure reasons (regardless of how much those snippets may or may not be sensitive, still have to maintain NDA). I know, Pastebin has a private mode, but it would still be a grey area to my bosses. They would argue that you can forget to mark it private and then the code is out there public.

I could save the snippets to a file, and then send them via IM or file share, but that's just a lot of hassle.

Ideally, i'm looking for something free.. open source or not doesn't matter. And i'm looking for something that's very fast to use without a lot of hassle for each snippit transfer, and is privateish between the sharer and sharee.

I was thinking about writing such a plug-in for VS, but if there's already something out there, i'd rather use that. So if you have any suggestions, i'd love to hear them.

EDIT:

I'm having a hard time believing s开发者_Python百科omething like this doesn't exist. It seems all the snippit managers are designed for long term storage and retrieval. Ideally, I'd like something like OneNote's "Side Note" that pops up a quick window, i can past something in it, then send it to a co-worker, then have that pop up in their screen. No storage, no archival, no keystroke integration to paste it into your code..

How about a shared Google Docs document?

If you are using GIT, you can easily email a patch or share to a common branch. One of the many benefits of using GIT :)
