Yes absolutely. I put forth a very simplified example to illustrate the point, but I assume any competent CPA (of which I am not so this is not actual advice) is going to tell you to try and separate out as much as possible that you can reasonably claim isn't "actual software development".
I'm more just frustrated at the need to do any of it, as the underlying principle is so anti-small-business. Why are we making anyone in the software field jump through all these extra hoops now just to keep their company viable?
