:)

note that this should probably go to kde-core-devel rather than kde-devel.

nice ...

less code is good and more features is good; my questions would be about 
libssh. it seems fairly young and it isn't used by many other apps yet (though 
it has to start somewhere, right?).

worst case scenarios would be that libssh either isn't developed anymore in 
the near future and/or it develops some serious bugs that don't get fixed. i 
suppose we could always roll back to the current kio_sftp at that point.

another issue is windows support; right now kio_sftp works on windows. the 
libssh website says: "Runs and tested under x86_64, x86, ARM, Sparc32, PPC 
under Linux, BSD, MacOSX and Solaris". if there is no windows support then 
that would be a regression for the windows side of things. (not that i'm a 
supporter or fan of windows, just stating the obvious points here :)

it doesn't seem to be very actively developed, but perhaps that's just because 
it works well and so doesn't need to be? in any case, i'd send an email first 
to Dawit Alemayehu (adawit at kde.org) since he seems to be the last active 
developer on it according to websvn; before hi there was segato porting it to 
windows.

that'd be a good feature indeed.

as long as the above issues aren't considered blockers by others or can be 
resolved in some fashion, this would be a good time to merge your code into 
trunk as we're starting a dev cycle. but i think the above issues should be 
addressed first :)

p.s. welcome to KDE development! :)
