    13 huh? you actually used ssh for that? i guess that's a fine optimization. 
    14 but for the general case the chunking should be homegrown (based on  
    15 dd and printf/read, i guess).

    19 I've tested the ssh ability to tunnel multiple session over the same 
    20  connection and it works nicely. There is one problem though - it is 
    21  supported only with SSH protocol v2.

    26 Unfortunately kde's fish implementation (as found in kioslave/fish  
    27 directory) is not a improvement in this particular case. At least I  
    28 do not see any code which deals with aborting a file transfer  
    29 gracefully. Most likely the connection is just killed.

    34 Sounds interesting - I'll take a look at it. My perl is pretty bad  
    35 though - I hope the code is not too complicated.

    40 no, i think we can do like ssh does, i.e., tunnel multiple virtual  
    41 connections through one physical connection. this adds some  
    42 overhead, though (especially cpu-wise, as we have to call dd for  
    43 every chunk). 
    44  
    45 btw, you might want to look at kde's fishserv.pl, it has some  
    46 optimizations. never looked at it myself, though.

    5011I was looking at the fish code recently and noticed that aborting 
    5112a running file transfer still causes MC to read the whole file sent  
    … …  
    6021open a separate FISH connection for the data transfer i.e. like FTP.
