Job board: node reference between cck nodes and webform

I'm building a job listing page on my website.

i've created a custom content that is displayed in a view, the job board, and every node has it's own reference field. I want to create a unique webform to apply to the jobs with a reference field that would auto populate from the node the user has selected telling me to which job the user is applying.

Any idea how to solve this?

I've found this example on the web that shows pretty much what I'm trying to do, but this isn't free and it's for a web based recruiting software. http://drupal.catsbeta.com/cats_jobsite/

Since I've done the job board and the webform, I only need to know how to cross references between both, so I think it's quite an expensive solution. Any suggestions will be appreciated.
