Meta Tags such as date/time in Text

[digitaltrails]

Could text-annotations support some meta-tags that expose some of the models current parameters? For example:

1. The date time of the current point of view.
2. Location/angle of the current point of view.
3. The current filename.
4. The date time last saved.
5. Things I haven't yet thought of.
   [/list=a] Does anyone have any insights as to whether this be cleanly feasible? If so, I don't mind looking into coding a patch.

It's seems that this suggestion is really only of interest to me, so I wrote a small plugin to do the job:
