I'd love to use Woobius (I think) if the price were lower. I work at an engineering firm with around 100 projects averaging 1 GB each. We can do some archiving, but the time it takes to be careful about that sort of thing across even a small organization is nontrivial. At their current prices, this would cost us $1500/month, which is at least twice as much as we'd pay.
It does appear to fill a need I feel acutely on a daily basis.
Also, the name "Woobius" is definitely not conducive to boss approval. To me, "Woobius" says not "secure, reliable CAD vault," but something closer to "fuzzy owl."
Daniel here, CTO of Woobius. I'd love to discuss how you want to use Woobius and how we could make the pricing work for you, if you would like. My email is daniel /at/ woobius /dot/ com. (if anyone else shares similar concerns, do contact me, I'm sure we can work something out that's suited to your specific needs).
Most industry collaboration tools cost hundreds up to thousands of dollars a month (or more for really large projects)... If anything, I'd say we're too cheap.
To be fair, this tool is designed for the collaboration that occurs between multiple companies, often with drawings (often as PDFs) rather than raw CAD files.
