Good practice for binary distributing

[Max Lapshin]

Hi!

As erlyvideo is growing to commercial distributing of code, I've got
new problem. I need to package some specific
parts of functionality into packages without source code.

Questions are:
1) is it possible to pack whole application into one java-like jar
file, where all required beams and app file will be?
2) what are practices for compiling modules into such binary
distribution: remove debug, etc. ?
