Argh! :-)

Rule of thumbs;

- total amount of faces in Blender x 200 bytes = memory consumption for  
faces/verts render.
- total amount of faces in File x 40 bytes = file size

Rough estimates! So, for 1 million faces:

- in memory: 200 MB
- in file:    40 MB

Since we still only use a 32 bits architecture, pointers can only span  
a 2 Gb area. That gives current realistic maxima of:

- to render: 10 Million faces
- that's in a file:  400 MB

This excluding shadowbuffers, texturemaps, particles, etc! When we move  
to a true 64 bits version of Blender (which is already possible on SGI  
for ages) we can easily go to:

to render: 2 Billion faces (400 Gig memory)
in file: 2 Billion faces (80 Gig)

Now, when will we reach that limit? If we anticipate with Moore's law,  
and define the practical maximum at 10 million faces for 2004, we get:

2005.july  20 M  (= need 64 bits version)
2007       40 M
2008.july  80 M
2010      160 M
2011.july 320 M
2012      640 M
2013.july 1280 M

Another upgrade in 2015! Thanks Hos! :-)
