It will be hard to get mirrors when we start out. here is my solution
Let say firefox if a pkg that can be install on pynux.
When a user types the command to install firefox here is what happens,
1. It goes to a web sever we have and brings back a simple text file
2. The simple file tells where to dowload the firefox source code.
3. The pkgtool checks dep. , that are listed in the simple file
4. Then it goes to the firefox site a grabs the source.
5. it grabs the deps. if it has to.
6. it compiles and installs.
What do you think of the idea.
