Why do you say that??
You are assuming they all make one connection at a time, all the time?
Masq has a limit on the number of simultaneous connections - normally 4096
per protocol (TCP, UDP & ICMP) - this can be modified within limits by
editing linux/include/net/ip_masq.h (however the max you could do would be
32K).

Connections are not the limitation. Nor is RAM. Your limit is the
bandwidth available. I guess a moderate spec PC would be OK to 2Mbit
connectivity (maybe less if it was doing PPP as well). Above that you are
probably hitting other limitations than sheer processing power - IO
throughput for example.
