Well you are dealing with static pages- the pcaps are static.  If you
just did a File->Save As for each page, save as a html file and
configure Apache to serve up the pages you'd be cool.  No reason your
pages have to be dynamically generated.  If all you have is pcap's to
work off of, Wireshark can save off streams to files.

Of course, Apache won't help you much beyond HTTP.

Anyways, at my day job we have to solve these kinds of problems.  To
do so, we tried classifying different protocols based on their
complexity and need for dynamic fields.  Long story short, protocols
are becoming more dynamic and are requiring greater inter-dependence.
Crypto which often has protection against replay attacks seems to be
showing up more and more.  Hence, like you, we're initially targeting
a smaller subset of use cases:

Anyways, I don't want to dissuade you from working on something like
flowreplay, even if it has limited protocol support.  There *is* a
need for this and no doubt you'd make quite a few people happy.
