Thanks for the work.  I did implement a more efficient packing scheme for the huff trees.  I will need to check out your build with the multiple header packets & merge them.

We really should get the huffman changes in there; there were some other things I did at that time, I need to review the code.

I guess that's me.  Unfortunately with the change in my employment status at On2, I haven't put as much time into this as I would like.  I've gone from being paid to work on it to a volunteer status.  That doesn't mean it won't get done, but I can't put an exact date on it.  I figure about a month of reasonably consistent work will get us to a reasonable place for beta release.  I'm hoping to put that month in starting in a couple weeks, so perhaps July 1 is a reasonabe date to look for.

Isn't the plan to integrate Ogg2 into this beta release?  How is that looking?
