No, it has not been tried, at least not by p5ee. Setting up a mailing list and one web page does not amount to much. If you really want this to work, you need to promote it. You also have to have something to promote, i.e. more than just ideas. This would mean a starter set of modules, a clear set of criteria for how modules are chosen, a procedure for nominating and approving modules, and possibly a separate distribution source which provides ready-to-use binaries or at least a one-shot source download with an automated build script. The p5ee project had no clear goal, and there were many people who wanted to define a new set of APIs rather than choose existing CPAN modules.
