I mean the idea is interesting and all (in theory - I didn't download the framework), but I gotta ask why you'd want to do this? C++ is appropriate and excellent for many problem domains...what is it about web development that should cause it to be added to that list?
Put another way: a lot of smart people have been making very good web apps for a while without using C++. Why is it that you're the first one to see that this domain is somewhere C++ will excel in, and what is it that you see that others don't that lead you to believe this?
I'm not saying that you're automatically wrong (great innovations tend to come from people who buck the existing mentality), but when you introduce something as distinctive and thought-provoking/dogma-challenging as this, you gotta provide more of a sales pitch than one table which says you're as good as Hibernate.
