A2K Link Directory Script

Hi,

I'm developing a link directory script for a client, but will have permission to give away the code.

It's being built as an SEO directory, and I am doing some very advanced SEO tactics with it (e.g. spoofing subdomains for each category and each listing).

Thing is, for those advanced options webmasters would need to be able to tweak their Linux/Apache boxes.

For example, subdomain wildcards are needed and the httpd.conf file needs tweaking.

So I'd like to get a handle on what percentage of webmasters have this stuff available to them, as if it's not too many, I won't waste time packaging my subdomain code for others to use and will keep it simple.
