Hi Stephan,

DIME would do the job - but you have an extra overhead of WSE to deal with
if it's not currently part of your design.

You could, quite easily, develop your own 'chunk' model to send multiple,
fixed-length byte arrays read from a BinaryReader; then 're-compiled' at the
server.

I would avoid BITS like to proverbial plague! We literally spent weeks
attempting to implement a solutions using MS's new baby. If you are
distributing to corporate clients who (like most) turn off Windows automatic
updates it will fail. More fundamentally, however, is its complete lack of
any method to deal with authenticating proxy servers!!! When BITS works it
is, indeed, very fast but, like I said 'avoid until MS get it working'!

Have you considered FTPing the data? The only 2 disadvantages I can see to
this are 1. has your client opened the correct port? and 2. you would have
to send the login and password details unencrypted (even if the resultant
connection were encrypted).

Hope this helps :)
