memory demands of REMD

Could someone who has experience running replica exchange simulations comment on the memory requirements of these type of simulations? Does it purely scale linearly with the number of replicas? For example, if it requires 450MB to run a traditional MD simulation on the structure, can I assume that it would take 4.5e4MB to run 100 replicas of this system? I can't seem to find any information searching on how namd handles this, but since it seems to just drive x number of different simultaneous simulations, this seems logical.
