Setting up pod on subdomain/subdirectory

Hello.

I have VPS with domain name example.com and trying to set up a pod. Using nginx as webserver.
I want my diaspora ID be like nao@example.com.
But I can’t run diaspora on the root of the site example.com/ because I have my personal site here already.

Is there any way to set web-interface for diaspora on subdomain pod.example.com or subdirectory example.com/pod/ or alternative port like example.com:8080? Like using MX record in e-mail or SRV record in XMPP.

Googling doesn’t give me much, I read about webfinger protocol, but I didn’t find much info how to hack it in Diaspora.
Sadly, I’m not ruby/rails developer.

No, it is not. If you use pod.example.com your diaspora ID is nao@pod.example.com and if you use example.com:8080 your diaspora ID is nao@example.com:8080. example.com/pod isn’t supported by the protocol.
