I bet it depends on IOS version and features.  I know of a customer
multihomed to us using a 3640 with 12.0T IP IOS and 2 sets of full routes.
148531 network entries and 296049 paths using 22692827 bytes of memory
55548 BGP path attribute entries using 7235600 bytes of memory

memory is getting quite tight.

               Head   Total(b)    Used(b)    Free(b)  Lowest(b) Largest(b)
Processor  60B11400   118418432   116611716    1806716    1547388     462604
      I/O   7C00000    4194304    1786360    2407944    2217100    2407900

I should probably warn them that it's time to start thinking about
either not being able to continue to take 2 sets of full routes or
upgrading to a larger DRAM capacity router.

I'd bet that with 12.2 or 12.3 code, this router would not be able to take
2 full views.
