You have my vote anyway but in terms of a business model i would hope that you don't drop the cost to use.
If I'm funded again I want to drop that to 100 Sats + 1.0%.
Not if you are still receiving funding from the DHF. At some stage that would be great if you can increase the user base and it starts to cover itself but IMO the end goal for any project should be self sustaining and help to grow the hive eco system.
You are right about the self sustaining but I think that only happens with bigger scale on both the Lightning side and Hive. Right now this is like a super cheap VC supported project and the VC is all of you who vote on the DHF.
