Toby:

Quick and dirty answer...  if they cannot stand the cost of a DS3,
it is worth considering that satellite costs might not be 'that much'
cheaper...  of course, price point, serivce vendor investigations
permitting.

But, something to think about is line of sight Microwave.. you could
potentially push the requisite sum of bits across such a link if you use a
good Tx-Rx frequency and is weather (rain etc.) is not a large
consideration.  Here too you have to consider: is TERM/length of service
need with the overall COST... frequency spectrum allocation and management
issues in the area etc.

But, as you suggest -- if your intent is to convince the client that this
is not doable (impossible/too expensive as you put it), I am sure you can
find enough reasons!  :)


Best.
