I haven't looked into that any further, but I'm putting that on my
agenda. Especially since the unit tests still seem to run through this
might as well be some kind of weird local / shell error (I'm using zsh

Well, the "server" part would probably be the same as some kind of new
--server option we introduce for netsync and this needs to be serialized
in the data stream to the server somehow, so of course once the code has
been adapted for that, it should just ignore it. We might have to
introduce another netsync version for this though.

Out of my head I'd have said "use the `include`" argument and let clone
check if only one include pattern is given (without expansion syntax),
but it might be better to have a dedicated branch argument for that. The
interesting question is how this argument is interpreted when used in
"normal" netsync operations - especially when further `include` and
`exclude` arguments are given. We could make it mutual exclusive, i.e.
either let them give a branch argument or a list of include / exclude
patterns, what do you think?

I don't think thats a good idea, because it puts the burden on the
person which manages this branch to keep all tools compilable and
running together, and at least for mtn-viz this is a problem, because
nobody took up the maintenance from Olivier for this until now.
No, I thought that only merging usher into monotone's dir makes the most
sense, because its a very useful and probably quite often needed
extension for monotone and we could tie both parts better together (f.e.
you wouldn't need to use your own copied basicio class). Just as mtnopt
is part of the distribution today, usher would be another supplement for

Well, I haven't looked at the code and its probably too different from
mtn's network code, but I imagined a new "proxy" mode in `mtn serve`
which would do just what usher does today. And we'd instantly also get a
server-side administrative console within mtn itself to manage the
server's running netsync connections and server setups. But thats
probably too much and too hard for now...
Let's concentrate first to put usher in a release-capable state so
packagers (like me :) can pick it up. If it packaged I'll have a much
easier way to convince the guys over there at indefero some time to
install and configure it as monotone helper for the use case.

Out of interest - what does this library do?
