I can.

I think the last one is in the "color SPU with ass (EOSD)" thread. I've 
implemented some kind of support of registering providers of EOSD bitmaps. 
I've ran into some difficulties with vf<->vo interface in the case of 
multiple providers, and, having very little spare time at that moment, forgot 
about it.

The last version of the patch, as I recall, works fine with vf_ass but there 
might be problems with vo_gl. Still the same code duplication argument: the 
scaling in spudec is done twice which seems unnecessary. And some of my 
questions in the thread were left unanswered.

The generators (EOSD providers) are very simple, there is no colorspace 
negotiation and so on. Maybe it is not needed here at all (probably nothing 
beside planar YUVA and packed RGBA will ever be used).
