These are the networking packages that I've used for my day-to-day work:
Comanche
Mysql drivers
RPC-XML
rST
VNCServer
None of these have ever been in the image. I'm sure there are quite a
few others out there as well.

Sure, but once I've done that, then what? Then I've got to maintain two
code bases. I won't be able to convert all these packages to use flow
in an afternoon. Most of them were written by somebody else, (as was
flow) so debugging them will take time as I figure out what is supposed
to happen as well as what actually is happening.
The other way would be to convert all these packages to use OldSocket
and friends and make sure I have always have flow installed in all my
images. Then I can port the packages one at a time, and still be able
to use the as-yet-unconverted packages at the same time. But if there
are any show-stoppers, I'm going to have a fair amount of work to move
back to the old socket code. And in the meantime I'm dependent on flow,
which complicates my image building process, even though I'm not using
it yet.
Don't get me wrong, I'm a big fan of ontological purity. But come on,
you're asking me to do a lot of work and take a big risk to preserve
the esthetics of your class names. How about a compromise? Just stick
FL at the beginning of each flow class to create a poor man's name
space. Then flow can happily along side the old network classes and we
can use the packaging system to sort out these problems.
