I may be getting old and feeble, recalling merely a discussion of what would
happen if the request were implemented.

I can't recall a specific instance of custom props failing with binary data
for me, so chalk that up to a lack of sleep until someone confirms/denies it
empirically.

However, i used to have issues sending compressed data over sockets until I
got into the habit of using base64.   But since I've never had a problem
using your excellent libUrl even those may have been user error. :) I
started using base64 early on in my works with sockets, so other factors may
have been at play while I was getting the hang of it.

But the issue seems bigger than Mark and myself:  I recall a number of cases
where using compress/decompress across platforms was discussed here as
problematic, though I don't recall if storing them in user props or
transmitting via sockets was a consistent part of the recipe.
