More documentation is great, so yeah, if you want a formal spec, go for it. @p{par}

Here's a tricky question you can start with: @p{par}

Assume there is a fork consisting of max-block-size blocks. How deep a fork/re-organization MUST a conforming implementation handle?  6 blocks? 1000 blocks?  as-many-blocks-as-there-are-in-the-chain blocks? @p{par}

Does that imply that a confirming implementation MUST be running with a certain amount of memory, or MUST a conforming implementation be able to handle such a chain fork within a certain amount of time? @p{par}

.. and once you answer all that:  what if the network consists entirely of non-conforming implementations that take shortcuts and just assume that there will never be a re-org more than X blocks deep?
