Late yesterday, one of the final features planned for 0.2 landed in Git; Linked SourceAssets.
With Linked SourceAssets, instead of uploading the asset to BitHorde, a new "-l" option to bhupload informs BitHorde of the local path of an existing file on disk.
This is great news for anyone interested in using BitHorde, while keeping assets visible in the normal filesystem for other applications.
For the next days at least, this new code, introducing lot of code-changes, will live in a separate branch daemon-asset-rework. Once more tested, it will be merged to the master branch, and 0.2beta1 will likely be released shortly after.
