A revenue share without a substantial investment is not possible - maybe someone totally green would give it a shot, and I wish you all the best with that. Try selling that business model to Zolo. It turns out that it is now possible to completely invent a word and have a million dollar online business.
I am not saying if you make money or don't make money. I know better than not to count someone else's money. I have my own challenges to deal with. For people like us who firmly planted their stakes in .ca, it is hard to let go. I think the business of domain names have mostly moved on. If you calculate all you have to pay in renewals and all your time spent on renewing, doing out bound marketing, or simply answering emails, you'd find, like most of the people out here sharing their thoughts on domains, you wouldn't be making much more than the minimum wage.
In Canada, we love and use our .CAs, but .CA as a domain investment has been a colossal failure.
If you own 1000 -1500 .ca domains for the last 20 years, you would've been a millionaire many times over if you invested that money in semi-detached homes.
That said, you can still have a domaining business I think, if you own 300,000 - 350,000 .coms and selling them between 2500-14990.
I never pushed you to make an investment or create a website. I simply openly discussed a possibility with you, and concluded over conversation. I was just surprised to see a couple of posts mentioning my idea that I had discussed with you in private. No biggie.
