1. log4YOUR_LANGUAGE_HERE: Currently log4j ports for other languages tend to be started on SourceForge, then have to endure incubation. If there was a moderately low-threshold way of starting the work under an ASF license, then there would not be a need to later sanitize the license and work to iron out any consistency issues.
2. UGLI-type efforts: Projects that don't fit neatly within the existing sub-projects but have potential (but not assurance) of helping the greater logging community.
3. New logging metaphors: Inversion of control, aspect oriented
4. Bridges between sub-projects. log4cxx appenders that dispatch log4net messages, etc.
There is already a logging-log4j-sandbox module that could be migrated to start LS Sandbox, but I'm not really familiar with it. I don't have a log4X that I'm just dying to get started, but it could be handy to have a place ready.
If this follows other Sandbox models, all LS committers would also have commit rights on the sandbox. If an outside developer wanted to start a log4X, they'd likely need to convince some existing developers to go along and the PMC to approve commit rights to the sandbox.
