Here's an open source Java implementation of a decompressor: http://www.freeutils.net/source/jtnef/rtfcompressed.jsp
Alas that's under the GPL, so can't be used in an official distribution of Tika. (You can use it yourself if you want though, but that would mean that your resultant program would be GPL'd too due to the viral nature of the license)
However, it looks from a quick glance at the docs on that site that it's very similar to visio compression.
If you're interested in working on this, I'd suggest we switch over to the POI dev list. I suspect that with the HDGF decompression code, and the documentation on the compression on freeutils, it shouldn't be too much work to implement a decoder.
