Image Investor as a professional tool

[PBittmann]

Hello,
we plan to build a little system with thousands of photos and were looking for a software that compares a single photo with the rest of the bunch. Image Investor seems to fit for this purpose. But we have a couple of questions about this product:
- We require Image Investor to be used from the Web. Is there a possibility?
- What kind of database does Image Investor use? Is this a market product? Is it multiuser? Can we bring our own database with us?
- Is there a support fee after we acquired the product? What price tag is there to be considered?
Would be nice to have some answers.
Best regards and thanks,
