they should both have (almost) 100MBit as they're connected with 
switches.. so the collision domains are broken up for each NIC.. 
right down to the VLAN'ed base-switch...

yeah.. but it's only one 100MBit that the services have to share on 
that NIC.. :) it doesn't matter, though.. we don't have that much 
load anyway (and if we have a peak, it's not critical) - it was just 
an example why I don't see a problem.. :)
