Don't think you are limited to what the admin UI shipping editor allows 
you to do, you can really do much much more with shipping in 
Interchange.  Did you look at the shipping.asc documentation that JT 
referenced?  In case you didn't it's at 

The shipping features of Interchange are really very robust and I highly 
doubt you'd need to modify the core's source to do anything fancy or 
unusual.  Also if you can't do it with just the shipping features then 
check out the recent post that Mike made to the mailing list about levies.

If you will elaborate on what exactly you want to do with shipping then 
I'm sure someone here can give you some more specific help.
