If you dislike /media directory (just as I do) and use plain, old /mnt for mounting various media (be it CDs, USB sticks) just use INSTALL_MASK in /etc/make.conf:
INSTALL_MASK="/media"
Simple, clean and working :)
Since my commit 301 to my overlay we have preliminary support for packaging Java web applications in Gentoo. First real application that uses it is blojsom - A Java-based, full-featured, multi-blog, multi-user software package, it has been added as commit 304.
Big fat warning: this is first release of this eclass, so strange things may happen - you've been warned.
