How big is the market for this I wonder? I run a product like it for free for 15 years now and while it has 100000s users and 1000s of companies running off it, there are only a few who would not skip to self hosted/cloud hosted instead of paying us. We are fully free (no pricing page) but we talk to our users and some sponsor us (just send some money to PayPal willy nilly when they feel like it) ; most of them say they like our solution better than others however they would just pop their own server if we would charge. Seeing how much excitement this brings, I guess I should try adding a pricing page and calling their bluff.
