I've started an open source project on Sourceforge to create a server for Mac OS X application distribution(Version tracking and update locations). Any volunteers are welcome, although knowledge of C and/or Objective-C is basically a must. Here's a brief description of VTAUS:
VTAUS(Pronounced V-Toss) Stands for "The Version Tracking and Updating System". It is a server initially for Mac OS X/Darwin. VTAUS will receive commands from client applications asking for the latest version and update location of a software package.
The address of the website is:
https://sourceforge.net/projects/vtaus/
I hope to see some of you signing up.
Thanks,
David Kopec
