FS extended attributes and FS notifications in Java.
There exists a class of problems that cannot be given a scalable solution with current J2SE. These include, for example, an enterprise file management solution, and a desktop search engine.
Imagine we have to develop a web-based interface for file uploading, with metadata storage (author, public/private flag, category, keywords), and with concurrent access to the file repository as a regular filesystem, for further categorization, renaming/moving, sorting, FTP access (important!). Due to missing filesystem extended attributes and filesystem notification support, a J2SE solution is going to be extremely inefficient. (I'm going to explain this further if there is an interest.)
Or, look at Beagle (http://www.beaglewiki.org/Main_Page). This desktop search engine, written in C#, makes extensive use of both Linux EAs and inotify.
I'll have to develop a minimal JNI bindings to POSIX EAs and SGI FAM and/or dnotify/inotify. I suppose there can be a community interest of including those features in Mustang (or maybe in Java 7.0). Please give me a tip where to look further, or, if this is not a correct place for making proposals like that, whom and where do I have to contact for collaboration.
