Is there any nginx module I could use to limit the number of HTTP POSTs from users to a certain limit. Say like 100 per 10 seconds from a single IP

Have you tried http://wiki.nginx.org/NginxHttpLimitReqModule?

I went thru its wiki page but i didnt see any place where it explicitly limits POST. I think GET would also get affected by this. any thoughts?

I would think it would be all requests also.There isn't anything specific for GET, HEAD, POST, PUT etc, to my knowledge. It probably wouldn't be terribly hard to implement if you know C (but I can't help you there :p). You can restrict your limit to a "location" block which can be a single script if that helps.
