I have a project in mind which would involve, multiple ESP8266's, BUT, I need to be able to control them individually via some unique identifier. I have some ideas using individual web server on each ESP, and unique IP address, but wondering if there is other ways using more of the capabilities that the ESP has, especially as this project idea could expand to several hundred ESP's

MAC address? See viewtopic.php?f=29&t=3587
Presumably the ESPs will be connecting to a WiFi access point (AP) and will get IP address using DHCP. A decent AP will provide DNS and will give each connecting ESP a hostname, and that hostname is likely to include the ESP's MAC address.
A separate problem: if you're going to have hundreds of ESPs, you'll likely exhaust the AP's DHCP range. And if you want to access them from outside that WiFi network (e.g. from elsewhere on the Internet), you also have a problem of routing connections into the ESPs' internal addresses.
