Did you think Satoshi put that limit in at 1MB to be there forever? 
No, I suspect he meant to add other mechanisms to control in-block spam in its place (or at least I might say, hoped to, but may not have known how to do it), but never got to it and no one else picked up that work either. Now we are kind of screwed.
How are we screwed if we have time to try to find solutions?
I meant screwed on the assumption that the 1 MB is about to fill up and cause problems.
But has anyone considered that a good solution may not even exist? Bitcoin is a new thing that has never been done before and is not a law of nature that Bitcoin must "work" in general (for example at larger scale).
In my experience in building software, often problems that get the kick-the-can treatment don't end up having good solutions later either. Maybe 1MB was satoshi kicking-the-can?
I'm not claiming this, just asking the question.
Well is good the same as perfect?
Certainly not

I believe there is a good solution but not a perfect one. Sounds like the solution may be a moving target (dynamic in nature).
I hope you are right but I don't really know if there is.
Most of these ideas that get thrown out are stuff that seems like a good idea but nobody can make a rigorous argument why they won't break.
