If you're talking about the "man in the middle", an observer on your
network intercepting network packets - then yes. Such an observer can see
what IP/ports are being connected to.
If you're using SSL, then the content of the conversation would be
impossible to decipher, cause the content would be encrypted. SSL is the
way to go for a secure service: it should be 1) an authentication mechanism
for a service, and 2) communication should be over SSL.
That said, it is impossible to hide IP/ports from an observer, therefore
there must be measures taken to build a reliable network serice:
proper redundancy
good monitoring & alerting
firewall to block offending subnets
properly geared operating systems (like SYN cookies support, tuned TCP
stack, etc)
load balancing
gradual service degradation mechanism
and so on

However I haven't decided for sure yet whether to go with JS or Lua yet.
