Yes and No. Subclipse uses a listener architecture that theoretically
supports this but which is currently fairly impossible for a 3rd party
plugin to use. The current trunk code, which will be used for our
next major release has changed this somewhat so that it would be
easier to use.

Correct, we do not.

No, support is not planned.

Sure. The Subclipse core plugin can be driven fairly easily by
another plugin. The Buckminster plugin, as an example, uses it to
provide SVN support. In our next release our plugin architecture will
be further changed so that one could also easily just use our
svnClientAdapter API if they just need SVN API access.

I think it will be fairly hard to integrate something like this with
Subversion. Depending on the quantity of the data in these files, you
might consider using Subversion properties to store this data. A
downside, is that merge support for properties is very poor in both
Subversion itself and most clients like Subclipse.
