Auto post from lead generation form on subsites

Wondering just how complex it would be to take front-end user inquiries from lead generation forms located on network subsites and post them to a job board...

for example say I've got a lead generation website for dentists in new york city, but no customer to send that lead to, so it gets posted on the Jobs & Experts board. scenario would be using a contact form to capture details.

alternatively if each subsite has the Jobs & Experts plugin installed can they be collated into a central network job board?

thnx
