Latest estimate: Internet Routing table / Memory needed

I haven't really seen anything on this in a while, in terms of an up to
date figure.  Here is what our internet border router reports (with full
from UUnet and Digex, and a few more (^3561$) directly from CW):

58909 network entries (116785/119858 paths) using 10448216 bytes of memory
15451 BGP path attribute entries using 1946036 bytes of memory
0 BGP route-map cache entries using 0 bytes of memory
2 BGP filter-list cache entries using 32 bytes of memory

Looks like I'm burning about 12 megs.  Lets say I had the whole table (~
58/59k networks today), but only one provider.  Rather than turning half
our Internet feed off to see, could someone tell me how this would affect
the above 'sh ip bgp summ' result from my router ??  I.e. how much memory
would be burnt then ??

Thanks in advance...
