	I think that's a matter that seems to be already decided.  People
want multihoming, redudnancy and such and are willing to put the burden
on the global routing table as a result.

	The result, people are upgrading router memory to the max, lots
of people have been asking recently about how much memory for a full
routing table, etc..

	I think the simple answer is:

	If you're using anything "recent" (ie: since 2001) you're going
to want to use 256m at minimum and ideally 512m-1g of dram in your system
with a reasonable cpu to process updates quickly.

	This is something that the market has really demanded (multihoming)
so the result is a global impact.  The statement "think globally, act
locally" comes to mind, but it's a tough problem as everyone depends on
their internet connectivity these days, so they want it to be
as reliable as possible.
