no way to use ioA for checking sfv when uploaded, it is only meant to be an addon, bot a sfvscript, for that you'll need to chose a zipscript, some are
- ioZS
http://www.iozs.com/
- PSio
http://www.snype.us/psio/
- zipscript-c
http://freier-koerper-kult.de/
- FTPLogger

PSio can be a good choice btw
