This would be a viable product. I've worked on a custom Web HR system for a Fortune 500 company, back before the dot com bubble came about and burst. Those ERP systems are way too complex, have lots of bloat, etc. for a small shop to need. Building something with base features of job posting, collect resumes (no forms to fill out, let people upload PDF or DOC), track applicants (notes, schedule interviews, etc.) Maybe build in features to allow applicants to link-in their internet profiles from Facebook, LinkedIn, etc. Find domain specific things to add - like for programmers it would be OSS/github linkage, lawyers might be some sort of link to case work? Maybe allow some calendar integration with the existing team so it would auto-schedule phone or in-person interviews. For example you just tell it to setup interviews for Thursdays or Fridays and it figures it out, contacts the applicant, blocks your calendars, etc. Allow applicants to then save their info, and then they can apply any other companies using the SaaS. Focus on the Applicant experience and the hiring manager experience aiming to simplify everything. I think the 37signals guys mentioned this problem space as something they might consider... as they grow their team I can imagine they would build themselves a tool to make their lives easier.
