Improving development process / help with developer setup

Hi,
I am looking for tips regarding improving the development process.  I'll
explain my current setup and please feel free to comment.

My developers all use windows + eclipse PDT, the workspace is hosted (via
samba) in a Linux server with Apache/PHP/MySQL.   I am in the process of
adopting Unit testing (PHPUnit2) and debug (Xdebug) so I have concerns about
how to property use this.

For example, in my current setup I'd have to enable SSH so they could run
the tests from the command line in the development server, but I am not sure
if I could remotely use Xdebug.

Thanks.
