I've no experience with the CarMetal branch of the Zirkel program, but I guess it will behave similar.
I may be wrong but i think that Carmetal is more than a branch of CaR. Let's say it's a fork with, now, very specific options. At first glance one could have the feeling that it is only a frontend to CaR but changes are deeper.

As for WIMS usage of the Zirkel applet; it is limited to visualisation of Wims-gererated data.
The applet receives these data as XML-string/file through the normal WIMS "getfile" method.
At this moment the GeoGebra-applet is used to check and grade a student construction/drawing.
This is due to the fact that GeoGebra includes a set of very handy javascript functions.
These public functions can selectively send/receive data.
There is even an OEF answer_type GeoGebra for this purpose.
Whereas the Zirkel-applet only has a single getConstruction() function ,
which sends the complete construction (...) as XML-string.
This is non-specific and hard to process.
If the author of CarMetal could include specific javascript functions (similar to GeoGebra) in the CarMetal-applet,
it would be a very fine enhancement of our WIMS system.
