This is definitely the best advise (other than mine) in this thread.
The best managers manage by doing, whether they do 1%, 10%, or 50%, if you do some, they will respect you.
The problem with seasoned programmers though is the inability to learn new things. I would first start by analyzing the code that they have written, and suggest improvements to them where applicable. You can stay on the business side of things (everyone who switches there does it because it's easier than programming) because that will give you maybe 10 hours of real work a week, and then do another 10 hours of programming a week, and you'll still live up to your manager title by not doing anything for 20 hours or more a week.
Best of luck friend, you'll need it. To me, seasoned typically means, head in ass and scared of ideas they didn't think of themselves.
