Software Deployment

I'd choose one that is on every machine like Adobe Reader. Almost everything is an MSI these days. Does that really answer your question? Can you say more about your environment, what mangement solution are you working with?

My suggesstion would be, First start with some simple msi's like WordWeb or your own msi etc.. This will give you confident and encourage you to do more deployment at initial stage..

Then you can go for the tough one..

Tough one, Get Orca and start playing with that?

Probably Adobe Flash player and Shockwave are the ones which are updated every month. So you can use them.

Might I ask what deployment tool/method you are using?
