This is a very specific feature request which only applies on 
source-hosted web applications and even for them its soemtimes not 
enough to just copy over the project contents, but start some build 
/ package process beforehands (*.war file for Java, *.egg for 
Python, *.phpar maybe in the future for PHP applications).

I'm afraid this is a bit out of scope for indefero. What could work 
however is to setup a post-push hook in IDF to call a command line 
script to do what you want to do, i.e. hot deployment of a 
development version of your webapp. What you need in such a case 
should already be there.
