I actually need this too right now, but without a pricing page I just move along.
I'm bombarded by vendors every day trying to "recapture" a sale, as part of an automated sales pipeline process.
I rarely provide contact details prior to being able to:
1) understand the product, what it does, and whether it will work for me
2) understand the pricing and sla
3) understand the business continuity model
I'd rather have a more difficult solution (selenium) that I know the above three points about than to get sucked into yet another sales pipeline.
