Jorgen caused some sort of explosion with his EnergyXT2 Linux beta, that acts as host for native Linux compiled VST plugins. Really awesome application - commercial one though.
kRAkEn/gORe coded an open source VST host for jack called JOST, and ported and coded a bunch of nice plugins.
So I felt like writing a set of ebuilds for all that, available in the Gentoo pro-audio overlay. There are over 100 plugins available atm! Enjoy!
