Android :: Using K9 To Push Hotmail - How It Works?

I know this has been discussed before, but I am looking to get an Android phone soon, coming from windows mobile, and have a few questions about getting email. With WinMO, there's an app to make hotmail push to my phone instantly, even though hotmail doesn't natively support push. From what I've read on here, the standard email app doesn't work with push from hotmail. But I really need to get this to work. I use my hotmail for my work, since my work server sucks. Frequently though out the day, everyone at work will get emails about upcoming work, and basically whoever responds first gets the job.

So having the phone check every 5 minutes wont do for me, since the job will probably already be taken. I have read about having gmail check the hotmail, but from what I can see, it will only poll every 5 minutes or so as well. I also heard about the K9 app, but from what I have read, it has some problems with hotmail. So, since I don't have an android to play with yet, for those of you who use K9 to push hotmail, how does it work? Are there any other options to get this to work? I've heard about setting up hotmail as an exchange server instead of an email server, but I'm not sure how that will work.
