Guy,
A router which belongs to multiple OSPF area's is called an Area
Border Router (ABR). All ABR's must belong to area 0 (The OSPF Backbone
area) in addition to any other areas they belong to. For each area a
router is a member of, it must store all of the LSA's for that area, and
Multiple areas on a single router means that SPF algorithm will be run
multiple times. This could be processor intensive, depending on how many
routers you have per area.

are you running full bgp routes on the router that you want to put 6 areas
on.

Core routers do this all the time. They end up being ABRs and you need to
make sure that the router has a lot of beef to it to be able to efficiently
handle all of the LSDBs thrown at it from each area.

couple of weeks ago I posted links to Cisco design documents that talked
about Cisco recommendations with regards to number of routers per area and
number of areas per router.
check out the design guides on CCO. follow the links to technical documents.
