it's become serializable again, at least jradford checked that 
yesterday/today.

do you want to get rid of libsl entirely? if not, i think it's not such 
a hot idea, i'm afraid we might end up basically forking libsl.

it seems to me that the libsl folks have been responsive so far and 
we've gotten the changes through that were needed (e.g., 
AssetType.Primitive -> Object, add serializable attribute back to 
LLUUID, PPC changes).
