EqEmu Zone limitations?

[generalzod]

Well after searching for quite a while, I was wondering if anyone knew what the technical limitations of EqEmu are, regarding
maximum user population and zone memory/cpu usage?
A graph/Matrix would be nice of user population, Emtpy as well
as maximums based on a few CPU choices. ie...

# of Zones | Population | Memory Req | NPCs | CPU needed
--------------------------------------------------------------------------------
1 25 users 256 MB 40 P3- 733 Mhz
1 50 users 512 MB 40 P4- 1.4 Ghz
5 100 Users 1000 MB 200 P4- 2.0 Ghz


just examples.. i have no idea if this is even realistic

I'm running 4 PCs, that I may test a new server on.

PC1:
3.4 Gightz Intel P4
1 Gig RDram
120 GigHD Ultra ATA 133
GeForce FX5600 Ultra
Windows XP Pro w/ Sp1

PC2:
(2) 1.2 Ghz P3 Intel (duel processors)
1 Gig SDRAM
75 Gig SCSI-3 Raid 5 (Seagate Cheetah hds)
GeForce MX460
Windows 2000 Server w/ Sp2

PC 3 & 4
IBM Thinkpads 733 mhz p3
256 MB SDram
20 Gig HD - generic 2.5 drives
3D accelleration by unknown but works - can play EQ on them

How many zones can I run theoretically on each of those
PCs or combined? Any ideas, Also how would I do some
kinda of distribution, so I can load different zones on each
of the laptops. I could just load the zones, close the lid on
the notebooks and put them in a dark corner.
