I noticed that even in Cauldron's Media Lottanzb is at 0.5.3, which is odd considering that 0.6 was released in January 2011. There is a big difference as 0.5.3 uses hellanzb as its' backend instead of SABnzbd like 0.6. Also although hellanzb, kwooty, etc. is available there is no package for SABnzbd. SABnzbd is by far the best and most popular application of it's type. I run SABnzbd on Cauldron without issues.
MGA Packages for CouchPotatoe, Sickbeard and Headphones would be nice as well; however, at the very least SABnzbd should be added and Lottanzb should be updated or elminated (@ as is) from MGA Media.
