Megatest

1. All run control access to db is direct.
2. All test machines must have megatest available
3. Tests may or may not have file system access to the originating
   run area. rsync is used to pull the test area to the home host
   if and only if the originating area can not be seen via file 
   system. NO LONGER TRUE. Rsync is used but file system must be visible.
4. All db access is done via the home host. NOT IMPLEMENTED YET.
