[Interest] Qt5 - my hopes for when the dust settles...

libQxt does the RPC (and zero conf)

QtIOCompressor is fine.  I use it all the time. There are patent issues with the .zip table, but QTIOComp supports the compression. See the example for  how to read the zip table though. 

And TAR is just a structure format.
header block
data blocks
zero block

You can trivially code an API around it. I did, when I was working with very large files. Somethign that emitted: TarEntryHeader(tarData)
TarEntryDataBlock(int n, QByteArray data)
TarEndOfFile() (double zero block)

There was a Model/View NG project...

Sending XML isn't the issue (and is wasteful of bandwidth anyway). I was
thinking of signals/slots that used RPC so that a client can emit a
signal thats recevied in a slot on a server and vice versa.

I think it needs a bit more work. And doesn't support .tar.
