With RC1 of Drupal 6 expected to be released this week, now is the time help update TinyMCE.
Beau Gunderson started a patch back in October, but it isn't finished/functional http://drupal.org/node/180436
I have just introduced Drupal as an aggregator to drive content to the Smarty driven, homebrew green social network code I inherited at my new gig. Now that I have a reason to use Drupal and TinyMCEat work, I'll be more active in helping to clear TinyMCE issues from the queue, submitting patches, and getting the patches committed to the release versions.
The good news is the TinyMCE module seems to work well with the beta releases of version 3 of TinyMCE from Moxiecode. Moxiecode had been hinting that they were dropping the current TinyMCE code base in favor of something smaller, but that hasn't happened... yet.
Not much going on with the editor agnostic WYSIWYG module either.
As always, I'll be the first to admit that TinyMCE is the best of some imperfect options. I can use all the help I can get to make this work for as many Drupal users as possible. To get this done we are going to need people to help write as well as test the patches submitted.
To do that, you'll need to install a test copy of RC1 of Drupal 6 when it is released and watch the issue queue for new patches.
