Just some comments ..

==

For binding ports <1024, there is at least one more option:

Since Linux kernel 2.6.24, the kernel supports associating capability sets with an executable file using setcap(8).

setcap 'cap_net_bind_service=+ep' <path to actual Python binary .. not a symlink!> 

http://linux.die.net/man/8/setcap
http://linux.die.net/man/7/capabilities

==

For maximum open FDs, if you run your stuff under a dedicated user, you can also modify

/etc/security/limits.conf

You will likely need to tune more options however .. like system wide max open FDs etc
