@Matt Please consider open sourcing v4 when you release v5.

You wouldn't need VC funding as you already have IPS Cloud business generating capital to invest in software development. Anyway, this is OT now, but it occurred to me that not having an open source version of your product is hindering your ability to grow to a large player in this industry.
And, I fear that you are about to lose even more third-party developers with your transition to v5 resulting in IC being a very niche product. Third-party developers are key to almost all successful growing internet companies.

Existing sales are not, but I'm thinking about accelerating future sales of IPS Cloud which I believe would be greatly accelerated with an open-source self-hosted version of v4 or v5, especially if you could get the price of entry-level IPS Cloud to under $20/month. A free tier of the open-source version with limited features could make conversion to paying user accelerate.
Anyway, this is my last comment on this... I just wanted to get you to consider open source as an option to scale your business. You need all the help you can get from third-party developers to accelerate adoption of IPS Cloud, IMHO.
