If you have ensured that your "third party" has a track record, sounds like a 
good plan.  If your "third party" does not have a track record, it can still 
be a good plan as long as they are either willing to prototype with your 
anticipated traffic or put certain monetary guarantees in place.

Your <<snipped>> ideas of using either data queues or MQSeries are also good, 
but be aware of the data space limitations of MQSeries and how slow it runs 
using persistence should a long-term outage occur.  To me, data queues sound 
better than 16Mb user spaces.

IMO, the _ONE_ thing that your e-commerce approach is missing is the same 
thing that most of them are -- real time ATP (available to promise).  Yes, 
you want to maximize speed to prevent surfing to competitor sites.  But do 
you want to end up like "Toys R Us" (or my winery >8(, for that matter) and 
have to call the client before a critical date about non-delivery when you 
could have done so on line?  Actually, my winery called on the due date and 
_STILL_ said the package I have yet to see would arrive on time, despite a 30 
day advance order.  Will _ANY_ of those "Toys R Us" clients do business over 
the web with critical delivery dates _EVER_ again?  I doubt it -- I know I 
won't be doing so with my winery any time soon...
