It is probably not much, but this is what I could find in a minute. many
VC system have a SCC complaint API (apart of the native). This protocol
was created by M$ is used by many systems so they are not bound to a
specific VC tool.

It's a closed-source, undocumented API that you can only get access to
by signing a Microsoft NDA.   From the WinMerge API:

	SCC API is closed API (no public documentation available) some
	IDE's (e.g. Visual Studio) use. There apparently have couple
	of reverse-engineered free implementations for SCC API. Status
	of those are unknown.

	WARNING: Be very sure you are not submitting any code behing
	NDA for WinMerge. WinMerge is Open Source so it is not legal
	to do. And what is worse it would prevent anybody reading that
	code working with SCC (and perhaps also VCS) support.

I don't really know what this interface is about, but:
 - For VS6 and newer, source control plugin can be implemented by creating
   a dll exporting particular set of controls. This is documented in help
   files that come with VS2005 SDK which is freely downloadable from M$ web,
   so I don't think that would be under NDA.
 - For VS2003 and newer (ie. the .NET based versions), plugins can be
   implemented for almost anything, including source control, by creating
   .net assembly exporting classes that implement some particular interfaces.
   These interfaces are documented in the abovementioned SDK, so again no NDA
   needed.
I actually started writing such plugin some months back, but since I can only
work on it at $work (don't have Windooze at ~, not to mention VS2005 license
-- the SDK is free to download, but requires full, non-express, studio) and
since it does not look like I could get them use Git at $work anytime soon,
I didn't work on it too much. Still I could share the basic skeleton and
the knowledge I have if somebody wanted to move that somewhere.
