The <<...>> syntax can cause only the first < to be encoded as < if there is no trailing space (e.g. <<something>> vs. << something >>). I suspect that I will have to manually look for any << and convert them. I guess this is technically an issue with Markdown and not MultiMarkdown, but it has apparently not come up before.

I tried to remove dependence on the varwidth package. This screws up the formatting of footnotes in tables, and also RTF exporting of tables. I'm not sure what to do - varwidth is incompatible with xcolor and is not a standard package. Suggestions welcome.

Creating a link to an image by label doesn't work properly anymore

I'm having difficulty with getting the glossary feature to work in the non-memoir classes. At some point I will look into this, but if someone else out there can point out what I'm doing wrong, let me know.

RTF support currently only exists for Mac OS X. Conversion from XHTML to RTF happens via Apples textutil tool. It is possible to write an XSLT file that converts from XHTML to RTF, but I have little to no interest in writing this myself, as I don't really use the RTF format very often. If someone were interested in developing this, I would help out. An added benefit would be that the XSLT could actually do a better job than Apple's tool in terms of footnote support and internal links. Contact me if you're interested. In the meantime, I suggest using Google Docs to import the XHTML file, and then export as an RTF. It does a much better job.

The sample MMD file creates two copies of the footnote in the MultiMarkdown vs. Crayons table, even though I only call for one. Not sure where the a footnote comes from.... Any help in tracking this down would be appreciated, as it didn't used to do this.
