Programmatically correct packages written in plain text format should
be loadable equally well in both the student and professional versions.
The crunch to which Martin is referring deals with an alternative 
binary format (.mx) in which packages may be stored.  These packages 
are created with the DumpSave[] function.  The format stores the 
definitions in an internal format that allows the kernel to load
the definitions more quickly.  The downsides are that the files are
platform specific (you can't load a Windows-generated .mx file into
a kernel running on a Solaris machine, for example) and that such
packages generated by a student kernel cannot be loaded in a 
professional kernel.
