Job execution through Xming

Hello,
Every evening I run few shell scripts on AIX Production Box, One shell script takes about one hour to complete and does some DB updation and application processing etc. The shell scripts are getting launched from prompt and not through cron or any scheduler as they require some manual inputs during execution.

I was thinking IF these shell scripts could be launched from Xming or any other xwindows tool instead of a normal emulator like putty or telnet etc. Will that benefit me incase network wire gets unplugged or by mistake I close putty window etc. I mean, will there be any benefit by running shells from Xming type of tool than running directly on production prompt? I have heard that running such things on xwindows emulator will run the job on production and accept manual input also plus during network intermittance will have no affect.

Please let me know your feedback.

Thank you
