I played around with this; indeed, the *.xpra file accepts a ssh= line.

However, it seems to me that arguments are parsed improperly.

When I use

ssh="plink.exe -noagent -i o:\pkey.ppk"

I get:

Error running ssh program '[plink.exe -noagent -i o:\pkey.ppk', '-l', 'lukas', '-ssh'....
[Error 2] The system cannot find the file specified

It seems that in this case, the complete command is interpreted as executeable which can of course indeed not be found.

When I use (without quotes)

ssh=plink.exe -noagent -i o:\pkey.ppk

then the appended arguments seem to be dropped; in any case they are ignored.

Independently from that, I see that xpra itself supplies "-agent" to plinks argument list. This might not be always wanted, for example in my case.
Therefore I would suggest to add a "ssh_args" option if it can be easily implemented.
If this is not set, do whatever is done now (with "ssh" executeable).
If this is set, these arguments are passed to "ssh", along with "-l username" and the command to be executed but otherwise no "default" arguments such as "-agent".

This method would also allow to pass "-load mysession" and hence GSSAPI authentication would work :-)
