Probably better to just use UDP directly.

Would work like this:

Client opens a reliable (TCP) connection to server.
Server identifies itself to client.
Client requests information about a file.
Server reports the file size, block size and number of blocks (num_blocks).
Client reserves hard drive space for the file.
Client requests that block 0 to num_blocks - 1 be sent to port P.
Server sends blocks to client via UDP on port P.  Each block has a
brief header with the block number.  1 block == 1 UDP packet.
Client keeps track of which blocks it receives and saves the data to
it's local copy of the file.
Server replies to client via TCP to indicate it's done sending.
Client requests whatever blocks are missing be sent to port P.
Server sends blocks to client via UDP on port P.
...
Client reports to the server that it has received all blocks and disconnects.
