I wonder could this be solved by having a /wiki:timemachine/ -path in the repo,
then put in a Node for each date, and put in a lot of properties with UUID
links to the particular pages/version instances.

I wonder if I understood this right... doesn't this imply creating such an node
each time _any_ page is changed, while this node contains uuids of all valid
page versions as of timestamp x?
If so, you'll run into severe performance problems.

Or, you could somehow use a separate workspace for each date - workspaces can
share Nodes in different paths as long as the UUID is the same.

That would be even worse!? Creating a new workspace every time a page is
changed?
I think saving any states is the wrong way here. The operation is too expensive
and infrequently needed.
It's a bit comparable to creating indices in databases: Sure you can create an
index for anything that's ever searched for, but this makes inserts and updates
very slow, since not only the data itself, but also the indices have to be
updated.
This is why I think this should be part of the application logic, which has to
search the repository on demand. What has to be modeled in the repository is
that deleted pages aren't removed upon deletion.

> Versioning and viewing the history is limited to one single page. If you want
> to see the whole wiki state as of timestamp X, you have to manually open the
> corresponding history entry of each page. Therefore, a time machine may be an
> interesting feature.
