The issue you might run into is dealing with pre-racked components that 
end up getting damaged in transit.  I've seen shippers do creative things 
with forklifts and pallet jacks :(

On the flip side, telcos often do this.  I know Verizon builds (or at 
least they did for a long time) racks and cabinets for deployment at 
customer deployment a central facility, then ships the finished product 
for installation.  In this area (Pittsburgh, PA), the cabinets were built 
and tested at a Verizon assembly facility in Martinsburg, WV.

If you do move ahead with this and do use 4-post cabinets, make sure most 
of the devices can be secured to both the front and rear posts.  That 
wouldn't apply to things like patch panels, but 1U servers and 1U network 
devices are often somewhat lacking in terms of sturdy mounting harrdware 
that's designed to accommodate the rigors of shipping.

As for shippers, I don't know if I would trust something as valuable or 
fragile to a regular LTL freight carrier.  You might want to look at 
someone like FedEx Custom Critical.  In my previous life, customers would 
ship their gear to our data center using them.  Not cheap by any 
stretch...  Also, if the source or destination does not have a real 
loading dock, your shipments will likely be more expensive if the shipper 
has to use a lift-gate truck.

Right.  Companies like Calzone Cases, Jan-Al, Penn Fabrication and Hardigg
can build cabinets for this purposes but they are designed for stuff that 
lives 'on the road', such as touring sound equipment.

There are shock-mount pallets and shipping frames that can be used - they 
often bolt to the bottom of the cabinet and then there is often a 'bumper' 
for the top of the cabinet and then the whole works is shrink-wrapped 
together.
