Can I use lighttpd/nginx for webdav but have updated disk usage statistics for mogile?

[dangalist at centrum.cz]

Do I need to upload all files to mogile over mogstored or I can do puts/gets over lighttpd/nginx and just 
keep mogstored running on background to collect disk usage infos?
I know there is support for lighttpd in mogstored, but how could I use nginx instead? Are there any disadvantages
of such setup?
