each chunk is signed to confirm the sender is allowed to post. many
packets are only ~100 bytes. for a large post (thousands of packets)
all that signing is no good (plus, signatures are nontrivially large
themselves)

a single large packet, I think, will go as a single large
chunk. otherwise the chunks have to survive across HTTP transactions
on the server, in some temporary pen, and that complicates things
rather a lot.

in other words, the 64k would be a "guideline" maximum chunk size,
which we'd flush any time we exceeded, but not a hard limit. we'd
always send an integral number of packets.

yeah, me too. there's a few ways to do this, but I do want to keep it
*relatively* easy.
