>> - libgit2 does not processes long paths. We workarounded the problem with tonel, but at a point we need to take care about this. Real problem with this is we need to contribute the solution to libgit2, but this is also good Open Source policy (contributing back).
>> - OSSubprocess in windows. We believe we need to extend OSSubprocess (our solution to communicate with system) to windows. And we believe is possible ;)
