Hmm, yes, sort of..:

I'm currently writing a MacApp-lication (to be exact, it's destined to be a
nifty News reader) which features a "TConnection" class which makes it pretty
easy to write asynchronous data transfer stuff.
I already have handlers for MacTCP and the File Manager; it's pretty easy to
add more.
The important point here is that it's asynchronous, which means that the user
can continue working while stuff is shuttled through the network.

The whole beast will be freely available, including source; however, it'll
take a while. I'm still working at the low-level stuff, currently debugging
a list class which stores variable-sized chunks of data (without requiring an
extra object for each chunk) and which can sort (via an AVL tree, which is
where the debugging comes from. ;-)
