That will almost certainly not be a problem. I'm working on reading stuff into git-specific structures and then updating those structures. I doubt any such code exists outside git. If it does, it's more likely derived from git than the other way around.

It's also worth noting that I'm aiming for the really low-level core stuff at first. It would be beneficial to get such simple things going as updating the index (with an entire file) and then creating a commit from that index. Such a thing would definitely be enough for (very basic) IDE integration, and then we can build further on that but utilizing developers from other projects than the git developer community.
