I totally agree with this. We've been in a firewalled world of NAT pain for so long that developers have largely forgotten how to think outside the client/server box it has imposed on us.
I feel this acutely every time I try and spread the word about my project (PageKite, a system for putting "servers" on mobile and personal devices). People just look at me funny and go "why would I want that when I can rent a vserver somewhere in the cloud?"
Once upon a time people would have asked "why do I have to rent some external machine instead of using this one I already own and this Internet connection I already have?".
