Linking to other nodes within text - suggestions?

I'm specifying a Drupal site which includes vast quantities of heavily structured textual data (footnotes, glossaries, indexes, cross-references, etc). I've been able to work through most of the requirements but I'm having trouble finding a good mechanism for linking nodes. Linking in a separate field is fine (use CCK Node Reference, specify views restricting which nodes can be displayed for linking, etc). The problem is when non-technical writers/editors need to link from within the body text.

The only options I've found so far are:

• http://drupal.org/project/ulink: This is getting there, but not great - it requires the (non-technical) editors to type in some arbitrary code and a keyword, wait a few seconds while results come up, then select from the full number of nodes in the entire site.
• http://drupal.org/project/linktocontent: The specifications look promising, but it's not compatible with recent D6 releases, and doesn't appear to be maintained.
• other link filters require the editor to know the NID, which isn't practical for the editors
• none of them appear to handle linking to anchors within other nodes

Ideally, what I'm looking for is:

• integration within WYSIWYG interface
• editor inserts cursor or selects text, then clicks a link button
• editor is presented with a browse-and-select interface listing nodes (visibility being determined by view/taxonomy/menu, etc)
• editor can select a node for linking - and ideally have the option to create an anchor point within that node

I can't be the first person who's needed this?... any suggestions gratefully received.
