The advantage with a postable source instead of a sitemap component as 
e.g. a transformer is that you can use it in any place where you want to 
access a block service. It would be rather easy to use it from non 
sitemap blocks. See

for an example of how to use the block protocol from a handwritten servlet.

See my answer to Alexander for a proposal on how to use a postable block 
source together with a new generator, transformer, serializer and reader 
for achiving what you ask for.
