I'm actually releasing a beta of my software/service that will initially have a strong focus on Network Documentation in the next couple of weeks if anyone is interested. I initially created it due to my frustration with Netdoc and it's now gotten to the point where it has various features netdoc does not have while being a fraction of the cost and much more pleasant to use. If you're interested, you can check out the website at www.flextory.com and send me an e-mail if you're interested in trying it out early before the beta launch in a week or two. Also, the site is a bit out of date (it'll be updated for the beta launch). There are more UI enhancements, a Reminder system, attribute data types, an API and more in addition to what's mentioned on the site. The software has also already won a couple different competitions.
The tentative plan is that the beta launch will last for three months and everything will be free. I'll also be more than happy to help anyone with data migration for the sake of getting some feedback on the system. After three months, it'll be a monthly subscription in the range of $50/month or so and I'll definitely be giving early adopters a discount.
Even if you have no interest in ultimately using it, I'd love to get as much feedback as possible on potential new features and bug fixes!
